The locomotive was designed as a hood unit to improve visibility for the engineer, essential for switching duties. Power was generated using a 6 cylinder Cummins HBI-600 diesel engine producing 150 hp (110 kW) at 1,800 rpm. This engine powered a single GE GT-1503 main generator, which in turn provided electricity to the single rear-mounted GE-733 traction motor which powered the rear axle. Power was provided to the forward axle using a chain drive. The unusual chain drive system for a locomotive was part of the reason for its top speed being limited to 20 mph (32 km/h).
