List of NJ Transit rolling stock

NJ Transit Rail Operations, the rail division of NJ Transit, operates a fleet of 175 locomotives and over 1,200 passenger cars. This rolling stock is used to operate NJ Transit's network of 11 lines.

Locomotives

Active revenue

These locomotives carry NJTR reporting marks for revenue service. Not included are the EMU cars, which are technically locomotives, but are listed in the passenger cars roster below.

Non-revenue

All non-revenue locomotives are diesel-powered and legally carry the same "NJTR" AAR reporting marks as all other equipment without exception. As these locomotives lack HEP, they do not haul trains in revenue service unless performing a rescue.

Model	Photo	Numbers	Year	Notes
EMD GP40-2		4300–4303	1965–1968	Ex-Conrail and New York Central. Mainly used for Yard Service and Equipment moves
EMD GP40PH-2		4102-4108, 4110-4112	1968	Modified for non-revenue use and are now mechanically standard GP40-2s. 4105, 4110, and 4112 remain unmodified.
MotivePower MP20B-3		1001–1005	2008	Rebuilt from 1967 EMD GP40FH-2s 4130–4134.

Multiple units

These trains are self-propelled, meaning they power themselves and don't require a locomotive for traction and HEP.
