NYC Transit is adding 28 new Motive Power Industries diesel-electric locomotives to its fleet of 62 such units that haul work trains and pumping equipment into sections of track where power to the third rail has been turned off to facilitate capital construction, maintenance work or repair damage.
The first locomotive arrived at the NYCTs facility on May 1, on a flat car from Boise, Idaho, where it originated two weeks prior and shipped cross-country over the rails and then off-loaded onto NYCT's tracks at Linden Yard. The locomotive will ultimately be transported to the Coney Island Shop for completion of conformance testing and other commissioning activities. All 28 locomotives are expected to be delivered by mid-2013. The new locomotives will add much needed resources to the existing fleet as well as replacing several units that have seen nearly a half century of service in the system.
Manufactured by MotivePower, Inc., this new fleet of diesel-electric switcher locomotives, termed R156, is custom designed and manufactured to meet NYCT's unique requirements such as tight tunnel clearances and strict weight limitations for bridges and elevated tracks. The units boast enhanced crew comfort and safety features, improved reliability and maintainability, and produce lower exhaust-level emissions than older equipment.
The R156 uses some of the latest NYCT subway passenger car components, which are service-proven and will result in more reliable operation and increased maintenance efficiency. The locomotives offer significant technological improvements, including AC propulsion, higher-horsepower, improved fuel efficiency, advanced emissions reduction technology and microprocessor controls. They also meet the latest crashworthiness and safety standards recommended by NYCT's Office of System Safety.
The locomotives feature an independent heating and battery charging (layover) system powered by a small diesel engine to keep the main engine warm during cold weather and provide auxiliary power to operate the lights and HVAC system, and to charge the batteries. This modern system reduces overall diesel engine emissions and while reducing fuel consumption during cold weather operations.
Additional features include advanced instrumentation and electronics, including a monitoring and diagnostic system with enhanced software, an automatic fire suppression system, and a sophisticated wheel slip and slide detection system. The new locomotive will also have cabinet space, electrical conduits and cabling allocated for future Communications Based Train Control (CBTC) implementation. – Information courtesy of the MTA
