YouTube videos of WI&M locomotive Number 22 working for Uncle Sam at Camp Claiborne, Louisiana:

The first half of this WWII-era Army film shows how Camp Claiborne trained military railroaders for their assignments in combat zones. At the 4:38 mark, former WI&M Consolidation Number 22 rolls out of the engine house to pull a train west toward Fort Polk

The second half of the same film shows how Army Railway Operating Battalions were prepared to keep their rail line open under any circumstances. Former WI&M 2-8-0 Number 22 leads the train.
