C3 (railcar)
 The C3 is a bi-level coach railroad car built by Kawasaki. These cars began delivery in 1997 ordered by the Metropolitan Transportation Authority for the Long Island Rail Road. The rail cars are pulled by EMD DE30AC and EMD DM30AC over both electrified and non-electrified territory. The C3 cars are powered by 480 V AC Head End Power (HEP) supplied from the locomotive through four train lines.
