Lima LRS-1200
The A-3174 (LRS-1200) was a model of 1,200 hp (895 kW) B-B diesel locomotive built by Lima-Hamilton in 1950. All sixteen units were built for the New York Central. A second order of 17 was outstanding at the time of Lima-Hamilton's merger with the Baldwin Locomotive Works, but owing to insufficient time to build the locomotives before the locomotive production ceased at Lima, NYC agreed to receive RS-12s from BLH, they were built at Eddystone, PA. Lima-Hamilton never assigned a model number to their models but referred to them by specification numbers. Model  designations such as "LRS-1200" were a railfan invention. Lima-Hamilton assigned A-3174 as the specification number for this particular unit. Most of these locomotives were retired in the mid-1960's, although two remained in service into the Penn Central era. 8062 and 8063 had their original Lima powerplants replaced with EMD V12 567C engines out of SW1200s and were finally retired in 1972.
