M7 (railcar)
The M7 is an electric multiple unit railroad car built by Bombardier, with delivery beginning in 2002, used by the MTA on the Long Island Rail Road (M7) and Metro-North Railroad (M7A). The M7 replaced the M1 railcars, which had previously provided electric service on these lines. The M7 fleets are powered from an electric third rail. A total of 1,172 M7 cars were built for the two railroads.
