 In April 2013, WMATA moved forward with plans to order 528 railcars from Kawasaki, called the 7000-series, to replace the 1000 and 4000-series cars, and to provide service for the Dulles Corridor Metrorail Project, otherwise known as the Silver Line.In a February 8, 2007 press release, Metro stated that the new 7000-series cars would have a similar appearance to the 6000-series cars manufactured by Alstom.However, in a January 2008 press release, Metro indicated that the design for the 7000-series cars would have a completely different appearance from that of the current rail cars.
