The A-3170 (LS-1200) is a diesel-electric switcher locomotive built between May 1950 and August 1951, by the Lima-Hamilton Corporation of Lima, Ohio, United States. Lima's original design was the A-3080, a 1,000 hp (750 kW) switcher, which became the standard for Lima's designs. A 660 hp (490 kW) switcher (proposed specification number A-3081) had also been designed at the request of American Rolling Mill Company, but none were built. By changing fuel rack settings, the A-3080 was upgraded to the A-3170 producing 1,200 horsepower (890 kW) from a turbocharged Hamilton T89SA 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. The Southern Pacific ordered 60 locomotives but agreed to receive 84 S12s from BLH instead.
