The GE 44-ton is an industrial engine that was actually designed for common-carrier service. The 1937 diesel agreement ruled that any engine weighing over 90,000 lbs required a fireman. The 44-tonner weighed in at 88,000 lbs, just under the limit. Industrial roads had no such restrictions and could run as big as a locomotive as they wished without a fireman.
