The Wabash Alloys Locomotive is a GE 25-ton diesel-electric locomotive built in 1940-43. Little is known about its early life, but from around 1970, it worked at Wabash Alloys, a producer of aluminum alloys, at Haskell, Arkansas.
The 25-ton model was the smallest locomotive in the GE range in the 1940s and 50s. It was designed for the small industrial user. With 150 hp (112 kW) and 15,000 lbf (67 kN) of tractive effort, it could pull half a dozen loaded cars on the level. Although the Arkansas nomination document asserts that "large Class I railroads would have used them for switching on light branch lines," standard freight cars of the time were up to 70 tons (64t) gross weight, or 17.5 tons (16t) per axle, so there was little need for 12.5 ton (11t) per axle locomotives on railroads, even on light branch lines, but GE built hundreds of them for industrial users.
