The Lima 750 and 800 hp switchers were diesel-electric switching locomotives built between November 1949 and June 1951, by Lima Locomotive Works of Lima, Ohio, U.S.A.. The LS-750 is a 750 horsepower (560 kW) switcher. It was later upgraded to 800 hp (600 kW) by changing fuel rack settings. Both models used the same turbocharged Hamilton T-69-SA four-stroke, six cylinder inline diesel engine, a Westinghouse generator and 4 Westinghouse traction motors.
All six LS750s were sold to a single railroad, with two being sold after the LS-800 had been introduced. The 23 LS-800s were sold to just two railroads.
Lima-Hamilton did not assign model numbers to their models but referred to them by specification numbers. Model designations such as LS-750 or LS-800 were a railfan invention. Lima-Hamilton assigned A-3149 as the specification number for the 750 hp model, and A-3171 as the specification number for the 800 hp model.
