The 203 series (203系) is an electric multiple unit (EMU) train type operated in Japan between 1982 and 2011 by Japanese National Railways (JNR) and later by East Japan Railway Company (JR East), and currently operated by KRL Jabodetabek in Indonesia and Philippine National Railways (PNR) in the Philippines.

Former 203 series (set 51) operated by KRL Jabodetabek in Indonesia, December 2011

Five former 203 series sets have been sent to KRL Jabodetabek (KCJ) in Jakarta, Indonesia. All trains are in operation in the Jabodetabek area with 8 cars per set, due to the short platforms at most stations in Indonesia.

Philippines

Former 203 series operated by PNR in the Philippines, July 2012

In November 2011, four former 203 series 10-car sets (set numbers 53, 54, 55, 67) were shipped to the Philippine National Railways (PNR) in the Philippines for use on diesel-hauled services south of Manila, replacing former Japanese 12 and 14 series coaches. As of October 2013, seven four-car sets had been formed, as shown below, with car "A" at the Alabang end. The units are equipped with a diesel-powered generator at one end to provide power for the doors, lighting, and air-conditioning.
