The LS-1200 is a diesel-electric switching locomotive built between May 1950 and August 1951, by Lima Locomotive Works of Lima, Ohio, United States. Lima's original design was the LS-1000, a 1,000 hp (750 kW) switcher, which became the standard for Lima's designs. A 660 hp (490 kW) switcher had also been designed, but none were built. By changing fuel rack settings, the LS-1000 was upgraded to the LS-1200, producing 1,200 horsepower (890 kW) from a turbocharged Hamilton T-89-SA four-stroke, eight cylinder inline diesel engine, a Westinghouse generator and 4 Westinghouse traction motors provided the 74,508 lbf (331.43 kN) of tractive effort.
Lima-Hamilton did not assign model numbers to their models but referred to them by specification numbers. Model designations such as LS-1200 were a railfan invention. Lima-Hamilton assigned A-3170 as the specification number for this particular unit.
