GE 75-TON DROP CAB DIESEL-ELECTRIC LOCOMOTIVE
The GE 75-ton Drop Cab was a diesel-electric Bo'Bo' locomotive built in 1944 by General Electric for the U.S. Army Transportation Corps. They were powered by two Cummins L1-600 diesel engines.
GE constructed ten the 75-ton drop-cab units for the US Army Transportation Corps in 1944 during World War II. Equipped with low-clearance cabs, they were based on the more powerful 80-ton locomotive; all of the 75-tonners were sent to France to help rebuild that country's rail network.
The Cummins model LI-600. Bore 7", stroke 9", displacement 346 cu. in., rated rpm 1,000.
Two of these units powered the GE 75-ton Drop Cab locomotive.
