Here's what I have on Badger:
Badger Army Ammunition Plant
Badger AAP, WI 53913
(608) 643 3361
DSN: 280 9361
The Badger Army Ammunition Plant utility rail system is operated by contract with the Olin Corporation. Covering 26.46 miles of track, it connects with the UP (ex-C&NW) and the Wisconsin & Calumet (formerly Milwaukee Road) on the south and east sides of the plant. Located eight miles south of Baraboo, the system formerly carried bulk propellants and acids over 75, 80, 85, and 110 pound rail, much of which dates to 1918; however, the rail operation is now almost totally inactive and is only used for occasional intra-plant movements. The enginehouse is located in Building 501. (Later notes: Base in inactive; site is used by 757th Transportation Battalion for training as well as rail car storage by RailCar Associates, PO Box 2967, Cleveland, TN 37320, PH 423-476-5677, FAX 423-476-2232.)
USA 1256 (formerly assigned to Detroit Army Tank Plant, MI)
Built in 1954
Rolling Stock: 100 30-ton flat cars, 17 30-ton wood box cars, 10 tank cars, and four ammonia tank cars.
The plant also possesses a yellow four-wheel Brookville locomotive not on the Army wide roster.
