and used the
Erie-Lackawanna Railroad's diesel-hauled commuter services. These railcars were named after the Jersey Central train
Blue Comet. These were considered state of the art at the time, due to their all-aluminum body shell construction as well as their use of head-end power (HEP). Their automated entrance doors, designed for use with low platforms only, earned them the nickname "Sliders". 155 cars were built, with 35 cab cars, 110 trailer coaches and 10
bar cars.
In 1987, the fleet was rebuilt by
Bombardier at
Barre, Vermont, with all 35 cab cars and a number of trailer cars receiving high doors, for ADA access and future compatibility with high platforms. They were given NJ Transit logos adjacent to the entrance doors at this time, as NJ Transit had taken over EL commuter service. The bar cars were converted to standard coaches.
The low door cars were retired from service in 2005. 25 of the cars were sold to

Metrolink in 2008 to help with an acute car shortage there. In March 2011, Metrolink returned the cars to FrontRunner upon the expiration of the lease. Metrolink also leased 15 cars directly from New Jersey Transit in 2009. These cars have not been used since 2011. The Comet I cars have become popular with western commuter lines as the low door setup is compatible with the low-platform stations in use. Eight Comet Is were sold to

NJ Transit retired the last of its Comet Is in March 2009. The Comets that were not sold to SEPTA, Metrolink, UTA or to private railroads and museum fleets were scrapped by 2010. FrontRunner retired their Comet I cars on April 18, 2022, citing increased maintenance costs and low ridership; they were put up for auction in October 2022, lasting until November 2022. In May 2023, the railcars previously taken out of service by UTA were painted with
HRMX railcar markings and numbering onto the sides of them while inside of UTA's FrontRunner train yard. They were transported to
Abilene and Smoky Valley Railroad in September 2023.

Comet III

The Comet III cars, ordered by NJ Transit in 1990, feature center doors and long end-doors, permitting end doors to open and close with traps open. The Metro-North
Shoreliner III fleet is a variation without long doors. The Comet III fleet was removed from revenue service between 2009-2010 and remained in storage until 2022, when it was decided to dispose of the cars as scrap. 46 of the 49 remaining cars were scrapped in June/July 2022 in Neptune Yard near the
Bradley Beach station, with one car remaining in NJ Transit's Meadowlands Maintenance Complex.
Metro-North also owns two Comet III cab cars, which were originally numbered 5179 and 5180. These cars were sold to NJT in 1998 and renumbered to 5009 and 5010, but were later sold back to Metro-North in 2008. In 2022, car 5010 was converted to a rail adhesion car; it was retrofitted with high-powered lasers to incinerate leaf residue.
Comet IV
The Comet IV cars, delivered in 1996 and purchased for NJ Transit's new
Midtown Direct service, are similar to the Comet III cars, except they have no door by the engineer's cab, have thicker black stripes along the window, exterior and interior LCD panels providing destination and station information, a new interior color scheme, and power operated saloon doors. The Metro-North
Shoreliner IV fleet is a variation without long doors.
With the completion of the Comet V order, Comet IV cab cars are no longer allowed to trail or lead a train; their cab controllers were deactivated in 2013. Since then, they are now used exclusively as blind coaches, in which they are inserted into a train consist and act as regular trailer cars.

Arrow I EMU cars originally built by the

The cars sat unused for several years, but realizing that the car bodies still had many decades of service left on them, NJ Transit made the decision to have them rebuilt into un-powered coaches. In 1987 and 1988 the cars were converted into cab control cars and trailer coaches by
Morrison-Knudsen for use on non-electrified lines. After two decades of service the Comet IB cars were retired by NJ Transit in late 2008, with some surplus cars temporarily leased to Exo's predecessor agency, the Agence métropolitaine de transport (AMT).
