what is it?

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.
