Under an agreement with the Metropolitan Transportation Authority (MTA) of New York, Bombardier Transportation is providing 1,172 M-7 Electric Multiple Units (EMUs) to the MTA’s two commuter railroads - the Long Island Rail Road and Metro-North Railroad - to replace their M-1 fleets.
The full M-7 fleet is maintaining a six-month average for Mean Distance Between Failure performance in excess of 400,000 miles (664,500 km) - well beyond initial customer expectations of 100,000 miles. The new M-7 cars also feature state-of-the-art rail transportation technology, including IGBT propulsion, energy efficient dynamic braking and on-board monitoring and diagnostic systems. Equipped as married pairs, the EMUs feature stainless steel carbodies for long life and low maintenance.
The units are equipped with Bombardier's renowned stainless steel carbodies for long life and low maintenance, and asynchronous AC motors featuring state-of-the-art IGBT (isolated gate bipolar transistors) inverters. Use of outboard-bearing bolsterless fabricated bogies offers considerable weight savings over cast bogies of previous generations.
Chartered in 1834, the Long Island Rail Road is both the largest commuter railroad and the oldest railroad in America operating under its original name. Metro-North is the second largest commuter railroad in the nation.
