The EMD DE30AC and DM30AC are a class of 46 locomotives built between 1997–1999 by Electro-Motive Division in the Super Steel Plant in Schenectady, New York, for the Long Island Rail Road of the Metropolitan Transportation Authority (MTA) in New York. Originally divided equally between the two types, the fleet currently consists of 24 DE30AC locomotives (diesel power only) and 20 DM30AC locomotives (diesel or third rail power).
