NJ TRANSIT to Replace Older River LINE Diesel Engines

NJ TRANSIT will replace its older light rail Tier I diesel engines on the River LINE with more than 20 Tier IV diesel engines from Cummins. The existing Tier I engines have reached the end of their useful life, with maintenance cost and time in the shop continuing to increase. 

The new engines will significantly improve fuel savings by 10 to 15 percent and align the line with current EPA emissions standards. Full implementation of the Tier IV engines should be completed by Spring 2022. Total cost for the project is approximately $700,000.

“NJ TRANSIT service gets people out of cars and is one the best ways to limit state-wide greenhouse gas emissions,” said Kevin Corbett, NJ TRANSIT president and CEO. “At the same time, these engines will help NJ TRANSIT reduce its carbon footprint and operating costs through better fuel efficiency.” 

The Tier IV engines are expected to reduce oxides of nitrogen emissions by at least 57 percent and lower particulate matter by 90 percent when compared to the current engines. The retrofit of new engines includes heating systems on the cars, installation of auxiliary power to reduce down time, upgraded control and diagnostic features, and enhancement of the fire suppression system.
