. Lima-Hamilton never assigned a model number to their models, but instead 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 model. Most of these locomotives were retired in the mid-1960's, although two remained in service into the Penn Central era. The surviving units, 8062 and 8063, were rebuilt to replace their original Lima prime movers with EMD V12 567C engines, like those in SW1200s and E8's. They were renumbered 8398-8399 in 1972 to make way for the new GP38-2's PC ordered, which were to be numbered 7940-8162. PC 8399 was retired in November 1974, and PC 8398 was retired in February 1975. No LRS-1200s survive today.
