The "original" WMATA Breda cars consist of the 2000 Series and 3000 Series cars before their rehab, as well as the 4000 Series. The 2000 Series cars were delivered between 1981 and 1983. They came with cam controllers and DC motors, had fewer seats than the Rohr 1000 Series cars and flip dot destination signs, among other features. The 3000 Series cars had chopper controllers but otherwise looked to be virtually identical to the 2000 Series cars when they were delivered between 1984 and 1988. The 4000 Series cars were delivered in between 1991 and 1993. These cars had a few cosmetic changes from the earlier 2000 Series and 3000 Series cars. The 2000 Series and 3000 Series cars were rehabilitated starting in 2002. As of November 2016, the 4000 Series cars, like the 1000 Series cars were following the 2009 Fort Totten Collision, were only being used in the middle of consists due to safety concerns about running these cars at the front or rear of trains. Although it had been planned to rehab the 4000 Series cars, WMATA ultimately decided to order additional 7000 Series cars and retire the 4000 Series cars instead. The 4000 Series cars were gradually withdrawn from service beginning in February 2017 and the last cars were decommissioned on June 25, 2017.
