Steam Department Update February 2015 Posted by Nigel Bennett in Steam Department at 16:54
Unfortunately not the update that I was hoping to be able to write 24 hours ago!.
The steam team has worked steadily thru a record cold February and made good progress, primarily on the Winter work on 1630. The work on the boiler was completed and the objective is to carry out an initial hydro test as soon as possible to ensure that nothing leaks on the backhead where it would be hidden by the refitting of the stoker and footplate. We really need some above freezing temperatures to safely run the heater that brings the water up to a suitable temperature for the pressure test. This has held us up for a week or so but the forecast suggests a “warm” day Tuesday so everything was planned. The tender was filled last weekend to allow the water to reach at least shop temperature. On Saturday the pipework was set up and a start made on filling the boiler.
Unfortunately this revealed that one stay seems to have broken during the process of clearing the tell-tale hole. A steady stream of water was apparent as we filled the boiler. With this stay plugged, we were able to fill the boiler and prove that this is the only stay in this condition. However, we now have a stay to replace. This was something that was not in the plan.
By end of day, Dennis had cut out the cab floor under the engineer’s area, the end of the stay in the firebox was ground flush and the stay cap had been removed. This proved rather reluctant and took a couple of attempts, otherwise we might have got the stay out. Anyway, we are now ready to remove it next week.
Replacing a flexible stay is something we did several times during the overhaul and can be done in a couple of weeks, provided we do not hit anything abnormal. However, it is additional work and means that the target of running Memorial weekend is now in some danger.
In parallel with the boiler work a lot of other work has progressed.
Dennis has put in many hours of work building up the yolk and other parts of the tender draw gear support mechanism. We should be receiving a rebuilt draw gear unit shortly and then the work can begin on making any modifications required to fit this under the tender.
A new pin has been machined for the front coupler pocket. The original was heavily worn. Once new bushes are machined and the support plate, that Dennis has rebuilt, is in place we should have a coupler that sits horizontal rather than sagging as it has in recent years!.
The air tanks are now refitted. This has been a big job as we have fitted new Teflon seals to the ball joints of the tanks. It sounds simple but replacing the very worn seals that have been there for many years can slightly alter the fit of the pipes. There is very little flexibility in large diameter steel pipes!. So in some cases we have had to cut and rethread the pipes to make the correct fit.
The new bush for the connecting rod is now complete and in place in the rod.
Dennis built up the brass on the securing disk. (My mistake. I said last month that the odd one came from a Mikado. Actually it is from a consolidation). Once that is machined we will have all the parts to reassemble the running gear.
However, the first steps at refitting suggest that, with the new bearing in place, clearance will be very tight and it may be necessary to remove and adjust the axle box shoes. Measurements that Jason has made indicate that the shoes are marginally thick and will need to be adjusted at some point. It may be that point is now!.
Work has been proceeding on the replacement of the gland packing on the air operated power reverser mechanism.
After a lot of effort the broken bolt in the smokebox front ring was successfully removed and a new one is in process of being fitted. John Heid joined us and was rapidly at work on this.
When the work on 1630 has relied more on welding and machining, people have been able to do some work in other areas.
Progress has accelerated on the Shay.
The big determinant of how quickly the Shay can be brought into service is whether we can clear the tell-tale holes on all stays behind the frames and motor brackets from inside the firebox. If all the tell-tales can be cleared to the required depth, we then need just to replace a number of stays in other areas that have been identified as bad and can then move quickly to re-tubing the boiler. If any stays need to be replaced behind the motor bracket, then we have a substantial project to remove and refit the motor in order to replace them.
Several people have been working on this as time permits but Phil is now working on the stays 3 days each week and making good progress. A lot of stays have been cleared so far. We all wait with bated breath to see if any prove beyond clearance in the critical areas. We should know within weeks now if we can avoid removing the motor.
Various work has been progressed to allow reassembly to move forward if the stay work is successful.
JD has been locating and preparing the various parts of the running boards.
Brian removed the equalizer air tank and cleaned it in preparation for hammer and hydro testing.
(Brian’s comment on this photograph was very fair!. “You could at least have taken a before shot to show just how much muck I had to remove”). Located under the cab floor, behind the engineer’s footstep this tank gets buried is everything thrown up by the wheels. Good job Brian!.
The riveting team, led by Stu, has put in several days on the cab. There are a LARGE number of small rivets to be placed but they are progressing and the number of temporary bolts showing on the cab is steadily reducing.
Once it is at temperature the rivet is struck on the anvil to dislodge any scale and then put into the hole.
The bucker holds the head of the rivet in position as Stu uses the air hammer to form the other end of the rivet inside the cab.
Although the basic method is the same, these are far smaller rivets than we had to use on 1630. Rather than fighting to ensure that the rivet is formed while still malleable, the risk with these is more that they can easily be over hammered and have unsightly deformed heads.
The process of Dennis building up with weld and Eric then machining to final dimensions has proceeded steadily thru the many components of the spring rigging. With this now largely complete, work has now started on machining the valve rods.
Mike returned this week after being out of state for some weeks and work restarted on the planer in preparation for the axle box work.
So March looks to be a busy and critical month. Wish us luck!. And if you fancy getting your hands dirty ………!!

Steam Department Update January 2015 Posted by Nigel Bennett in Steam Department at 20:38
There is nothing like hunkering down for a big Winter storm to create time to update the blog!. There was a very good turnout at the steam shop yesterday (and I suspect a nil turnout today judging by the white out that can be seen on the webcams!!). As we reach the end of January a lot has been done in the steam shop so far this Winter ….. and there remains a lot to be done before May!.
Obviously the absolute priority is #1630 and getting her ready for the new season. While she was out of service the critical focus was on rebuilding the axle boxes on the trailing axle and the 15 year boiler inspection. Known or suspected issues were addressed during this time but we did not do a complete “tear-down” of areas that were within tolerances and had given no indication of problems.
So, for some years to come our Winter program will include the annual maintenance items and a program of inspection and remediation where required of some other areas each year.
The annual inspection work has progressed steadily. This is essentially in four stages:
The large majority of the inspection work is now done. Among other task:
We now have to test the gauges and finish checking of the arch tubes and we will be ready to carry out the hydrostatic test when the weather permits.
The other areas where major work is taking place this Winter include:
In the normal way when dealing with and elderly steam locomotive none of these has proved as simple as initially hoped!.
The rods between #4 and #5 axles have been removed and the dimensions carefully checked. The clear issue is excess wear in the FS #5 rod bearing. Material has been obtained and a new brass bearing will be machined and fitted to the rod. The other peculiarity is the disk that sits behind the securing nut and forms the outer face of the ES #5 rod bearing. The peculiarity is that it differs from the other similar disks and bears the number of a long gone Frisco mikado!. It is suspected that the difference can lead to steel on steel contact where the original pattern would always bear brass on brass. It may be that this was why this bearing was always the one that had a tendency to run warm. Dennis can add brass that will then be machined to match the original #1630 parts.
This shows the stock ready for machining the new rod bearing and, on the bench behind this, the disk that will be built up then machined to better match the original #1630 pattern.
An intensive inspection of the couplers has indicated no cracking of any of the large parts but some damaged internal parts that go a long way to explaining tricky operation. The good thing is that these are standard couplers so spares should not be an issue. The trouble is that removing the couplers has led to detection of more work needed on the draw gear.
Under the tender significant wear was found in the mechanism that provides “shock absorption” when backing onto or pushing a train. While not an immediate concern with the weight of trains handled at IRM, it was decided to give this area a thorough overhaul.
The following pictures show the work involved in detail
This is what you are used to seeing
Behind this, under the tender, the coupler is backed by this assembly. The coupler is attached to the cage assembly by a substantial pin that is inserted or removed from below and held in place by the bolt that can be seen at center in this picture.
Looking further back (actually toward the front of the tender) you can see the cage and, substantially hidden above it, the outer edges of the shock absorber.
First the bolt is removed, the pin dropped and this allows the coupler to be removed. Here you can see the hole thru which the pin fits to secure the coupler to the drawgear. The pin is actually a substantial rectangular block with rounded ends.
Having removed and separated the cage and shock absorber the empty cage clearly shows how the pin secures this to the coupler.
And here we have the “problem child”. The heavy frame of the shock absorber still has the massive springs in the wider part of the casting. Information suggests that these huge springs are compressed about an inch when fitted and you do not touch these without special equipment!. The empty end of the casting is the location of the smaller springs that were removed in many pieces.
Dennis will build up the mountings under the tender where there is significant wear. Meanwhile there is a lot of discussion on how to deal with the shock absorber. The original unit has two groups of springs, one fairly substantial and one VERY large. The clear intent seems to be that the smaller ones provide an initial softening of the impact while the big ones take the load after these are compressed. In our case, the smaller springs were smashed to pieces and clearly had been for a long time. Two avenues are being investigated for repairs. A source has been identified that could produce replacement for the broken springs while the original manufacturer is still in business and does produce modern equivalent units that are still used in freight cars (as those fitted to #1630 were in 1920). Initial feedback from the spring supplier is interesting, suggesting that the (1918) design is defective as the smaller springs would have a very short life and be likely to fracture pretty quickly in exactly the way that had happened on #1630!. We have no idea if the design was changed but it does suggest that, if a modern equivalent can be installed without major modification to the tender, this would be the best solution.
The flexible stays hidden under the footplate behind the stoker riser have all been inspected cleaned and recapped. A good deal of rust damage was found in the footplate supports. It is interesting that much of the corrosion stems from modifications made to fit the stoker, probably in the late 1930’s. The center of the cab floor has to be raised to provide space for the coal delivery to the stoker. To provide a level floor to the cab raised sections were installed on both sides of the cab sitting on top of the original floor to provide a surface about 3 inches higher. This created a double skin in which a lot of corrosion has occurred. Much of this has been repaired and the remaining action will be to rebuild the center section around the stoker delivery pipes. This places a lot of pressure on getting the hydro done as soon as possible. We do not want to re-install the stoker delivery pipes until we are satisfied that the flexi caps have passed hydro testing. But we have a lot of work on rebuilding the cab floor that requires these pipes to be back in place!.
After a great deal of work this weekend the area under the ES footplate is clean and partly reassembled. Here you can see the fabrication that sits below the grate shakers and converts the rotation of the shafts in the cab floor to a back and fore movement of rods attached to the grates.
The air filter site behind the compressor under the smokebox and on top of the main frame. It is basically a large cartridge filter where you release a bolt securing the housing, drop the housing and cartridge, then re-install with a new or cleaned cartridge. Simple!, except that it was mounted so that the housing has insufficient space above the main frame to allow it to be dropped. We know that 2 years ago we did manage to get it off but this year a large number of us in 4 hours work could not find a way of doing so. Eventually we decided to cut the bar on which it is mounted and modify it to have bolts that can be released to remove the whole filter. Interesting. When cutting the bar it was apparent that we were following the line of a previous cut and weld. So it seems that this is not a new problem!.
The stoker motor is now in the shop awaiting attention when essential work for this season has been done. Last weekend a few of us opened the cylinders, applied lots of oil and then tried turning it with substantial bars. Actually, while it took a good deal of effort to get initial movement, once it started to move and oil spread on the bores and rings, it now moves very smoothly and easily.
As time permits some work continues on the other projects.
On the Shay,
So. A lot of progress has been made but there remains a lot to be done to ensure that #1630 is ready for running in May. We will be hard at work each weekend and some weekdays. We are always looking for new people willing to get their hands dirty!.
Let’s hope we do not get many storms like the one today. I suspect that it will be a couple of days before it is practical to get back to Union!.
Sunday, December 7. 2014
A lot of people have pointed out that it is an awfully long time since there was a Steam Department blog update. In my defense I plead that work in my role as Museum Treasurer has been nearly full time (sounds better that pleading idleness or incompetence!). So here we are, an update of several months of work in the department.
Doesn’t time fly!. It seems like only yesterday that we were working all night to get ready for the pre-season inspection. Now the operating season is over and the Winter work program is well under way. #1630 is back in the shop and we are busily crawling over and into her to so what must be done before next season.
It was a very successful season overall. We only missed one scheduled day due to mechanical problems. (Unfortunately Father’s Day when we had to fix a leaking valve).
It was rather challenging to begin with. She seemed to use a lot of coal to keep steam up but, once we reached fresh coal, she ran a great deal better. I guess it should not be a great surprise. Coal that has been lying around for years has lost quite a lot of the flammable material so you shovel a lot more for the same effect!.
Late in the season we had a scheduled weekend out of service and this provided the opportunity for a good clean. Aside from the usual coaling and watering, the boiler was drained and refilled with fresh water, the paintwork was washed and the rods cleaned and oiled.
After all the work she looked a lot better. The dust was gone from the top of the boiler but she is developing a “working” look as the condensation from the safety valves and generator slowly discolors the paint on the firebox sheet metal.
I fired the last two Sundays. That is quite an experience to really be part of the working locomotive after so long crawling in, over and around her as a dead object in the shop. #1630 certainly is different from other locomotives I have fired. I was working out that it is about 50 years since I first fired a locomotive (Prince on the Festiniog Railway). The box is a lot longer and wider than anything I have fired before. So a good deal more throwing. However, on the demonstration line, she is only running for a few minutes at a fraction of her real load capability. Very different from a small locomotive working flat out for a long time. You would certainly have extreme difficulty keeping up with #1630 if she had a full freight load behind her unless the stoker was operating. In museum service the trick is to achieve a relatively thin fire without any gaps when you are operating and not to have too much at the end of each run. Having a significant amount of hot fire when you get back to Union can lead to a noisy lay-over!.
So what has been going on in the shop and what is planned?. Obviously #1630 will be first priority for Winter work and a lot must be done this Winter to have her running for Memorial Day next year.
She is due for both the 30 day inspection and annual inspections which amount to quite a lot of work. The annual inspection requires the drawbars to be removed, checked and annealed. While the tender is separated and the drawbar removed, we will do the inspection and testing of the stays under the footplate. In addition we want to thoroughly examine the rear axle bearings and rods. There was a tendency to run warm in the rod bearings and more knocking than we would like. So the plan is strip, measure and carefully examine everything in this area and try to improve the running next year.
Before we could even start the work there were two busy weekends of preparation. First the locomotive had to be run on air to thoroughly remove water from all the steam system in case of any freezing during the Winter, Then there was the cleaning!. I missed the air running but was able to participate fully in the cleaning!. 3 hours with a high pressure hose in the firebox blowing soot out of the tubes is an experience to be missed if possible. The jokes of your “friends” when you emerge black from head to toe are also to be avoided!.
With this done she was moved into the shop and the locomotive and tender were separated. This provided some interesting views of the locomotive cab and the way in which the tender is attached. The center drawbar is spring loaded and is what pulls the tender and train. The two outer bars are a safety mechanism should the drawbar fail in service.
Above the drawbar can be seen the end of the auger of the stoker. This is turned by a steam motor in the tender (of which more anon) to drive coal along the large steel pipe from the tender to the locomotive. Looking again at the locomotive with part of the footplate removed you can see the way that the cast pipe carries the coal up toward the fire door.
In this view the fire-hole door has already been removed. This large casting would connect the end of the delivery chute to the fire-hole. Behind the closed door of the firebox, coal would be driven up the chute to the delivery plate where steam jets would throw it forward into the firebox.
After considerably more work, the delivery system and the central footplate had been removed to reveal the back of the firebox.
After several weekends of work to do this stripping the actual inspection that necessitates it took only a few hours. A group of flexible stays hidden behind the stoker delivery chute do not have telltale holes and, as such, must be inspected every 7 years. They all proved to be sound so that part of the inspection is done. Unfortunately we found quite a bit of rust in the supports of the footplate on the fireman’s side so Dennis will need to do some rebuilding before we put things back together.
Another job being progressed is the rebuilding of the stoker. This is not essential but we would like the stoker to be operational at least for demonstration purposes. It is not clear how useful it would be in museum service where we need only a thin but even fire. If it can be made to work we will find out!.
First stage is to remove the stoker motor. This is located behind a panel in the tender on the fireman’s side. Here it is being carefully eased out of the tender. This gives little idea of the effort that went into this exercise. It was an extremely tight fit and some modification of the hole was required to get it out with the fork lift. We suspect that it may previously have been fitted and removed on a greased plate so that it could be turned first one way then the other as the hole was not big enough for it to come thru directly.
Last weekend we carried out the last major stripping exercise. The locomotive was temporarily reattached to its tender so that it could be moved a few feet back and then forward. The objective is to remove the connecting rods between axles 4 and 5 to allow measurement and checking of the rod bearings and alignment of the two axles. The move is necessary because the pins in #4 axle are removed by driving them back thru the wheel between two spokes …. And you cannot remove the pins on both sides with the wheels in any single position!. Here Jason and Phil are removing the rod from the Fireman’s side. By7 end of day both rods were removed.
A lot of other work is in progress on 1630.
Most of the strays have now been opened up (removing the fireclay that seals them in service) and checked. (We must ensure each year that the telltale holes are open).
Both large air tanks have been removed and subjected to hammer and hydro testing. They are now ready for refitting.
Inspection of the air compressor is under way. The steam feed line has been removed and will be replaced. This line shows significant corrosion so the decision has been made to replace it.
At the end of the summer the tender and cab of #938 were repainted (Thank you Roger!). She now looks a lot better. In addition, Phil, JD and Brian removed the tubes from the boiler. This was largely an investigation exercise. We really had little idea of the condition of the boiler of this locomotive. The conclusion was that the interior of the boiler seems to be in reasonable condition so there would be no obvious barrier to rebuilding it. That does not indicate any likelihood that this will happen any time soon. The fact that the boiler appears reasonable indicates that it she is not a “no hoper”. Given the work that would be required, all we need is a dedicated Rock Island enthusiast with $500,000 or so burning a hole in his pocket and she could run again.
The second big focus has been the Shay and this will be our major project thru the Winter. The major jobs on the Shay are
Replacement of a number of firebox stays;
Rebuilding the front beam; and
Rebuilding the smokebox.
Once these are done, we can get on to the “more routine” jobs of re-tubing and re-assembling.
There is still some uncertainty over whether we will need to replace some stays behind the motor. This would require removing the motor and the bracket on which it sits, making the job rather bigger. While working to determine if the motor removal will be necessary we are progressing other work that is independent of this decision and ensuring that we are as ready as possible to do the motor removal if required.
Over the Summer:
The front truck has been prepared for remounting and placed back under the locomotive. This may not be permanent. Depending upon the need to lift the boiler we might need to pull it out again to fit the new bottom of the smokebox;
Everything under the locomotive was cleaned and painted before refitting the truck;
JD and Cody have been steadily removing stays that are identified as bad and in need of replacement (generally due to blockage of the tell-tale holes);
The parts for the front beam have been located and we are starting work on preparing these. The coupler and its mounting pocket have been moved down to the fabrication area for Jane to needle chip and wire brush. Once they have been examined for any cracks they can be painted and prepared for use;
David and I worked on the grease nipples in the drive shaft and couplings. First conclusion – a Shay has a LOT of these. All will need to be cleaned, checked and replaced if not working correctly;
Work was also starting on lapping all of the key steam valves. This led to the discovery that there were cracks in the face of the main turret valve. Clearly it was over tightened at some point. A new one will need to be made;
Work has also progressed steadily on #428
Dennis has been building up the axle boxes ready for machining. Unfortunately a problem developed with the planer and we are waiting for parts that will hopefully make this operational and ready to machine these axle boxes;
Work was also progressed on repairs to the frame that will allow the rear spacer to be refitted.
A great deal of machine work has been carried out to produce new parts that will allow the springs to be refitted.
Ed has been working steadily at refitting the pipework of the cab. This is an “interesting” exercise. It is a 3-D jigsaw of pipes of various diameters, shapes and end connections. I will post a photograph next time but he has achieved remarkable progress in turning what was a random jumble of pipework into a fitted backhead. It is all the more of a challenge as some of the pipes link to the air pump – which is not there to check if that is what a particular pipe should link to, and one or two seem to have been added to the pile from other locomotives!.
So, overall a lot has been done and there is much to be done in the next few months. If you are prepared to get your hands dirty, there is no shortage of work if we are to have 1630 back in service for the season and move forward with the Shay!.
I am now heading to the UK for Christmas so will be away for a few weeks and look forward to more progress when I get back and a busy Winter ahead in the Steam shop.

Steam Department Update 08-10-2014 Posted by Nigel Bennett in Steam Department at 14:50
It promises to be a busy few weekends ahead for #1630. We are planned to run both weekends of Day Out With Thomas and then Labor Day weekend.
She ran well in recent weeks and I was able to see her in action and take a few pictures when I came for the Vintage transport Sunday. My collection of photographs of her in action is limited as I am normally in the shop when she is running.
There was some pressure to get preparation work done last week / last weekend as it was suggested (as it has been several times before!) that the track contractor would be on site this week preventing #1630 being set on the service track.
So a lot of effort went in to #1630 to ensure that everything is ready for three weekends of continuous operation. The first two weekends will be particularly challenging as we need to be out at the depot by 10:00 to clear the way for the Thomas trains. That will require a much earlier start time for the crews.
Aside from the usual coaling and watering, the boiler was drained and refilled with fresh water and the locomotive had a good clean. The paintwork was washed and the rods cleaned and oiled.
After all the work she looked a lot better. The dust is gone from the top of the boiler but she is developing a “working” look as the condensation from the safety valves and generator slowly discolors the paint on the firebox sheet metal.
Good news for the firemen is that we have just about reached the end of the old coal and a new supply has been delivered. The large part of what is now in the tender is the new batch. So the hope is that we should be using less and burning better … which would be a big benefit to the firemen on a hot Summer’s day!!.
Good thing we believed the story this time!. On Monday the contractor was on-site and hard at work.
By early afternoon the track in front of the boxcar was gone and grading for the switch was progressing fast. Difficult to recognize that this is where #1630 was standing in the previous picture.
If work goes to plan, the switch and much of the cut off track will be in place before next weekend.
In the shop continued progress has been made on the Shay. Over successive weeks, the under-side was first thoroughly cleaned by needle chipping and wire brushing. Then mid-week Christian and his brother finished the cleaning and primed all the surfaces. Finally, last weekend Jane put in hours of work in painting the whole area. As the day progressed, it became clear that the overall area was far bigger than it first appeared. There are all sorts of surfaces at different angles and it seemed that whenever she looked from a different angle, there was another area of primer still to be covered. However, after a hard day’s work, she had it pretty much complete. And very nice it now looks. A couple of jobs on the truck and hopefully we can get it back in.
The next couple of weeks may be quiet in the shop as we have intensive running and also the Thomas weekends that keep the site “rather busy”!

Steam Department Update 07-24-2014 Posted by Nigel Bennett in Steam Department at 16:14
It was a rather limited turnout last weekend but some key work was achieved.
#1630 was not scheduled to run as it was the diesel parade weekend. It is now planned that she will run next weekend (7/26-27) and the one day of Vintage Transport (Sunday August 3rd). Subsequent dates in August are being finalized based upon availability of our small pool of qualified crew. However, the tentative dates would have her out of service the weekend of August 9th and running during the Thomas weekends (16th and 23rd). These dates are not yet firm.
Some odd jobs were done but one critical task will ensure that photographs before and after July 19th will be very easy to distinguish.
After a break, Dennis returned and worked with Jerry to letter the cab. She now has the Frisco lettering back on the cab sides.
This involved the careful application of the stencils that Dennis had sourced.
After these were carefully placed and flattened, the covering sheet was removed.
Some of us thought that the black on yellow lettering was rather attractive and suggested running for a while with this!!.
However, the purists prevailed and, after careful masking of the cab side vents, the lettering was sprayed.
So we are now back to a more complete appearance with the cab correctly lettered. Note that she will always look different in this running period as it has been determined that the “IRYM” identification, that she carried previously, is not required and will not be re-applied this time.
The other job was to remove and repair a bracket under the tender, that supports part of the brake linkage. This had shown signs of looseness and movement so it was removed, corrected and re-fitted.
In what is becoming a regular Wednesday activity, a full load of coal was lifted into the tender. Thanks again to Anthony from B&G for operating the skidder to fill the tipping bucket for raising on the forklift. We used the shop forklift this week as the big B&G one was in use. I will not be doing that again in a hurry!!. It does the job just fine. However, due to its smaller size, you are much more up close and personal with the coal tipper. So each time Anthony fills the tipper you enjoy a nice cloud of coal dust and his amusement as he watches you disappear in the black cloud!. You also have to be really careful to watch out for any loose lumps of coal that may fall when lifting the bucket into the tender.
The other hard and messy job that is done most Wednesdays is to fully clean out the grates and ash pan then inspect the firebox. Phil and JD have regularly been doing this and the results of their efforts are a good starting point for the Saturday crew.
Not a good photograph but it gives some idea of the area previously covered by clinker and cinders that the guys have to clean out each week.
Work has progressed in several areas on #938
Ben did a great job on cleaning off the pipework under the cab (and incidentally finding and removing some old bird’s nests that lay above and behind them).
I spent much of the day wire brushing and needle chipping the firebox crown. It is a pretty filthy job but rewarding when you actually get it to the stage where it can be primed.
The long and tedious job of needle chipping the tender frames continued. One side done and the other well under way.
Phil cleaned off much of the boiler barrel and also moved forward with needle chipping the tender. We had considered trying to uncover and measure the logos and identification on the tender as a basis for making stencils. However, it is far from clear how much the side logos were original or part of work done in Texas. We therefore decided that it will be more effective to work from photographs. The paint was carefully removed to see if anything unusual showed up. And it certainly did!.
Phil had carefully removed paint on the back of the tender and determined that the pattern agreed closely with photographs with the capacity at top and the locomotive number below. He had also picked out the outline of the three large numerals 938. However, as he worked into the body of the numerals we got a surprise. What we had assumed was an 8 clearly had no central bar and is very definitely not an 8 but a 0. So our tender was not originally from 938 but 930.
Tom is checking the boiler number against ALCO records to confirm that the loco is 938 but stampings on various motion parts seem to indicate that it is. So it looks as if the tender was swapped late in life. The good photograph that we have of the locomotive clearly shows a distinctive pattern of repairs and a large bulge in the side identifying what we now know to be the #930 tender. However, this is a very late photograph. So now we have an interesting research project on what happened to 930 and when. Was this just a last minute swap when 938 was tidied up for the end of steam display or did she run with this tender in later years?
So another week of steady progress.

Steam Department Update 07-17-2014 Posted by Nigel Bennett in Steam Department at 20:39
It continues to absorb a lot of time to run #1630 but we have now started to see more jobs moving in parallel with the operations.Recently #1630 has run as scheduled. Unfortunately we will now be running less frequently, generally every other weekend due to the shortage of trained crews. Brian came up from Florida for two weeks and allowed us to run all weekend days in the last two weeks but now we have guys on vacation and it is more difficult.
Last week required a lot of effort to get ready for the weekend.
Anyway, the good news is that she has run reliably despite these issues and the coal pile is now down to not much more than one week’s supply. After that we can get some new stuff and hopefully get beyond the uncertainty.
Work has progressed in a number of areas and plans for the next projects are becoming clearer.
Aside from the Winter work on #1630 our main projects will be the Shay and #428. Much of the work on the latter is welding and machining so most people will be working on the Shay.
In addition, before #1630 comes in for the Winter, the objective is to get a coat of paint on #938. This is the first of a whole lot of static display engines that sorely need such treatment.
So a lot has been happening and there will hopefully be more in the next few weeks when we are able to run #1630 rather less.

Steam Department Update 06-27-2014 Posted by Nigel Bennett in Steam Department at 17:15
An interesting couple of weeks as we get used to supporting the operation of #1630 while starting various jobs that have been in the background while we focused on the overhaul. I am struggling with when best to write a blog these days. Much more work is taking place on Sundays and mid-week. So my practice of writing a blog each Saturday would largely reflect work in progress with the key being to have everything complete for running the next Saturday!.
Father’s Day was, to say the least, frustrating!. I was not at the shop on the Saturday as my son from the UK was over with his wife and our little grand-daughter. Like a lot of other people our plans for the Sunday went awry when we got to Union expecting a trip with #1630 and found her stopped. The crew on Sunday morning found excessive leakage overnight from a union in the cab and she was not fired up until this was fixed. Unfortunately it was early afternoon before the union was suitably tightened and late afternoon before test runs were carried out. At least these were successful so she was fully operational by end of that day.
This weekend (21st/22nd) was scheduled for maintenance and Saturday was a busy day working thru a list of minor issues that had been identified by crews over the last few weekends.
There is a surprising amount of running maintenance required on a steam engine providing a good reason why we need a weekend out of service every few weeks to cover all these “little” jobs. One surprising routine job is cleaning grass and stalks off the FS rods. We seem to have a crazy bird that seems intent on building a nest behind the small air tank. Seems like a pretty stupid bird as it does not get beyond a loose heap of vegetation behind the tank each week. This gets removed or falls off but the fact that it steams and goes away for a while does not seem to stop it trying again the next week!.
In other areas quite a lot has been going on.
On #428 several activities have got under way.
On the Shay, work has resumed on the front truck. This is now being painted in preparation to refit the springs and allow it to be refitted to the locomotive.

No decision has been made as to what we're doing with 902.

Luke, The 902 was the victim of a very serious fire that heavily damaged it, pretty much beyond the point of reasonable restoration or repair. So [...]

I had a question about MBTA 902, I herd it is going to be scrapped and used for parts. Is this true?
