The M8 is an electric multiple unit railroad car built by for use on the New Haven Line of the Metro-North Railroad. It replaced the fleet of 244 M2s which entered service in 1973-1974, as well as 54 M4s and 48 M6s which entered service in 1987-1988 and 1994 respectively.
The M8 is similar in design to the M7 car used on the Harlem Line and the Hudson Line. Like the M7, the M8 is able to pick up 750 Volt DC direct current power from underruning third rail for operation along the New Haven Line from Grand Central Terminal to Pelham, where the traction power source is transferred to the overhead catenary wire. The overhead wire is at a nominal 12.5 kV AC power from overhead lines via pantographs for operation from Pelham, New York to New Haven, Connecticut (as well as along the New Canaan Branch), and 25 kV AC power from catenary for operation along the Shore Line East route east of New Haven to New London, Conn. Unlike in earlier classes, changeover between the two AC voltages can be made by the engineer while on the move.
In response to rising number of people seeking to use their bicycle to solve the "last mile" problem between Metro-North stations and destinations, ConnDOT has pledged to provide bike racks for storage of two bicycles in the disabled riders area of each rail car. In the event that a disabled rider boards a car, all cyclists must move their bicycles to the entry vestibule. In spite of the hook installation, during peak travel periods only folding bicycles are permitted aboard most Metro North trains.
