When MP&ES purchased this unit, it had been re-configured as a cabless Auto-Haul type locomotive. All that was in place were two phone-booth type operator stations where the operator stood. MP&ES removed the old ALCO engine and installed a Tier-3 compliant gen-set with an updated PLC control system and updated operator interface. Our customer had taken an ALCO locomotive, which did not meet any emission standard, out of service. With their MP&ES replacement ALCO locomotive, the customer is now very satisfied with the fuel savings, performance, and the knowledge that the locomotive is more environmentally friendly.
