The 203 series sets were on through services between the Joban Line and Tokyo Metro Chiyoda Line until they were replaced by E233-2000 series EMUs, and finally withdrawn from services in Japan in September 2011.


The sets were formed as follows.[3]

Cars 3, 6, and 9 were each fitted with one PS21 pantograph.[3]




The trains were gradually replaced by new E233-2000 series EMUs, and the last set ran in revenue service on 26 September 2011.[4]


On March 20, 1995, the train number A725K, or the Matsudo Train Set Number 67, which later transferred to Philippine National Railways in 2011, was involved on the sarin gas attack which was happened on the Tokyo Metro Chiyoda Line alone, southwest-bound section bound for Yoyogi-Uehara station at 7:48 AM, As the train approached Shin-Ochanomizu Station, the central business district in Chiyoda, one member of the team punctured one of his two bags of sarin, leaving the other untouched, and exited the train at Shin-Ochanomizu. And then finally, the train has been proceeded down the line with the punctured bag of sarin leaking until 4 stops later at Kasumigaseki Station. There, the bags were removed and eventually disposed of by station attendants, of whom two died. The train continued on to the next station where it was completely stopped, evacuated and cleaned.

Overseas operations


Five former 203 series ten-car sets (Set numbers 51, 52, 66, 68, 69) were shipped to Kereta Commuter Indonesia (KCI) in Jakarta, Indonesia in 2011. The trainsets were subsequently reformed to create four trainsets formed as one eight-car set (set 108), two ten-car sets (sets 106 and 109), and one twelve-car set (set 2).[5] One ten-car set, set 109, has 5+5 formation with two middle driving trailers which are used only during regular maintenance.[5]


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.[6] As of October 2013, seven four-car sets had been formed, as shown below, with car "A" at the Alabang end.[6] The units are equipped with a diesel-powered generator at one end to provide power for the doors, lighting, and air-conditioning.[6]

Due to wear and tear, the airconditioning units of the 203 series have currently bogged down.

In 2014, PNR started to operate the EMUs in 5-car configuration. As of December 2018, there are five sets in operation.

EMUs 3, 4 and 7 were divided among the other EMUs to form the 5 sets, and their remnants are stored as reserve units or source of spare parts.
