New Jersey Transit last week announced the agency will replace 20 aging diesel engines in its River Line light-rail fleet to align with current emissions standards and realize as much as 15 percent in fuel savings.
The 15-year-old Tier I engines now operating on River Line light-rail vehicles have reached the end of their useful life and will be replaced with Tier IV diesel engines from Cummins, NJ Transit officials said in a press release.
The Tier IV engines are expected to reduce nitrogen oxide emissions by at least 57 percent and lower particulate matter by 90 percent.
“These engines will help NJ Transit reduce its carbon footprint and operating costs through better fuel efficiency,” said NJ Transit President and Chief Executive Officer Kevin Corbett.
As part of the $23 million engine retrofit, crews will install heating systems on the rail cars, install auxiliary power to reduce down time, upgrade control and diagnostic features, and enhance the fire suppression system.
The upgrades will extend River Line vehicles' useful life by 30 years, agency officials said. Full implementation of the Tier IV engines will be completed in 2022.
