Green Bay & Western ALCo RSD-15 #2407 (formerly with Lake Superior & Ishpeming, originally with the Santa Fe) moves from the station track to the enginehouse at the Illinois Railway Museum in Union, IL. It was built for the Santa Fe as their #841 in 1959, and retired from service with the GB&W in 1989, being sent to IRM in 1996. After a long period of disuse, it was finally restored and started up again last year. Due to the long front low noses of the RSD-15s, they were nicknamed "Alligators". Unfortunately, I didn't get a good shot of that aspect of this unit. Chicago Great Western caboose #601 is in the background.
