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. Preserved examples are located at several museums, including the Whippany Railway Museum in Whippany, New Jersey and the Southern California Railway Museum in Perris, California. Comet II The Comet II cars were built by Bombardier Transportation, which acquired the rights to the railcar's design from Pullman. The first order of cars was built for NJ Transit between 1982 and 1983 and consisted of 142 trailer coaches and 19 cab cars. A second order, the Comet IIB, was purchased in 1988. These cars feature long end-doors with trapdoors over the stairs for use at both low-platform and high-platform stations. The cars are similar to the MBTA's BTC-1 and CTC-1 cars, built in 1978 by Pullman Standard. These cars were intended for use on lines formerly operated by the Central Railroad of New Jersey, operator of the Blue Comet train to Atlantic City. This led to the NJ Transit series of single-level cars becoming known as Comets. These cars have been overhauled by AAI Corporation and Alstom between 1999 and 2003 to make them aesthetically and technologically similar to the Comet IV series and are now compatible with later equipment. Shoreliner I and II coaches, purchased by Metro-North and the Connecticut Department of Transportation for use on non-electrified territories east of the Hudson River, are variations without long doors. Amtrak's Horizon coaches are also a variation without long, automatic doors. Metro-North also purchased Comet II coaches for use on the Port Jervis Line, where they ran until replaced by the Comet V. The Comet II cars have since been transferred to the East-of-Hudson pool, where they remain in service. SEPTA Regional Rail and AMT also purchased cars based on this class. 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. 48 of the 49 remaining cars were scrapped in June/July 2022 in Neptune Yard near the Bradley Beach station, with
