Andrew, to better answer your question, no CNW 411 was not the power on the train. 411 is scheduled to return to service in 2017. The IRM Diesel Shop is presently completing the restoration work being performed in the cab and electrical cabinet.
There has been a rumor going around the CNW Dash-9 twins are now owned by the Museum. Is this true, or are they still "in storage"? If memory serves correctly, Union Pacific was still storing them there.
I really hope that the museum gets to keep the twins. Personally, Union Pacific is my favorite modern railroad but the Chicago and Northwestern is my all time favorite. It would be a shame if these last 2 Dash 9s in C&NW paint were patched or splashed in UP paint. I always admire the units when I visit and I'm never disappointed.
It is very, VERY unlikely that Union Pacific will patch or repaint the CNW twin, since they recognize their "historical significance". Time will tell as to how much longer the twins will be in regular service, but I am willing to bet that when the time comes, they will be donated to IRM. But I don't know if that'll be any time soon. It seems a bit too soon for locomotives like Dash-9s to be put in museums, as they are not quite as old as say SD40s or U-boats and the Class 1s that have them are still using them on a regular basis. However, on the other hand, the Dash-9s are getting up there in years. Who knows, maybe we'll get a surprise later this year.
