Of the total number of M8 cars, 292 have been accepted for service with 20 more being inspected and tested by the builder, Kawasaki Rail Car Inc.
The new M8 trains represent more than half of the train cars used for weekday service on the New Haven Line and more than three-quarters of those cars on the weekends, according to the MTA.
As of April 2013, the New Haven Line was operating more M8 cars than old equipment.
Metro-North ordered 380 M8 rail cars from Kawasaki in 2006 for use on the New Haven Line. Of the 380 original order, the first 38 were built in Kobe, Japan, and the remaining 342 are being built at Kawasaki's plant in Lincoln, Neb.
