The restored Milwaukee Road 4-8-4 No 261 rolling thru Columbus, Wisconsin (at speed!) on its way back to Milwaukee on 08-17-08.
This is a 1944 CMStP&P Alco locomotive brought back into service in 1993. Many more photos and information can be found -Here-.
Update: I recently noticed that this engine was incorporated in the Johnny Depp movie, "Public Enemies", (2009).
Coincidentally, principal photography for the movie began in March 2008 in Columbus, Wisconsin where this photo was taken.
Old 261 can be seen slowly pulling into Grand Central Station (Chicago) at the 44 minute mark of the story.
