National Railway Equipment

NREC sells new and rebuilt locomotives to railroad companies worldwide, with an emphasis on the North American market.

NRE's flagship locomotive product is dubbed the N-ViroMotive[1] and is targeted at providing light duty road switcher engines with increased efficiency and decreased air and noise pollution.

They use a low hood design with up to three diesel generator sets (gensets) that supply power to the traction motors.

The current gensets use a 700 horsepower (522 kW) Cummins diesel engine and can be easily swapped in and out for repair or overhaul work.

As of 2009, NREC has sold upwards of 210 N-ViroMotives to many different railroads, including the U.S. Army, with the largest order of 60 being delivered to the Union Pacific which plans to use them in the smog conscious L.A.
