I have a pretty interesting idea/question. Being 1630 always seems to use the milk tanker for extra water or to use as a water source why not rebuild the Kansas City Southern Tender that arrived a couple weeks back? Could make a great auxiliary tender for when she's out on the line or for testing purposes such as this. Just an idea.
Hyde,
Who knows for the future. The KCS tender is far from usable at present and would require a lot of work to make it serviceable.
Would 1630 and train look better with two tenders as opposed to an express car next to the loco ?. Matter of choice I think.
