The 203 series is a Japanese commuter electric multiple unit operated by the Japanese National Railways and its successor the East Japan Railway Company from November 1982 to September 2011.
History[]
The 203 series was conceived in 1982 to replace the older 103-1000 series sets that were used for through-running to and from the Jōban and Eidan Chiyoda Lines. High-speed acceleration and deceleration was still required, so the trains were based on the older 201 series, while having aluminum bodies to help save weight and lower costs of production.
Some sets were used for close to 30 years, and as such, their age began to show; as such, the sets were slowly retired starting from 2010 when they were replaced by the newer E233-2000 series sets. The last remaining set, MaTo55, was used for a special Thank You 203 series run on 26 September 2011, following which it was withdrawn and being exported to Indonesia for KRL Jabodetabek and to The Phillipines for PNR Tutuban Line.
Due to lack of overhead catenary in Philippines, the 203 series trains operated by PNR, is hauled with 900 class locomotive and a generator is used to powering electricity (aircon, compressor, lighting, etc.) on each train. The air conditioner in PNR 203 is now using the INKA-made ICOND ACI-4202.
The JR 203-106 are the first 203 series to bearing the KAI Commuter gray-red-white livery, while set 203-109 are adopts the latest color scheme in September 2023.
Design[]
The 203 series uses a traditional design very much like most commuter trains of the time, with "emerald green" accents. What set the 203 series apart from other trains used by JNR at the time was their use of unpainted aluminum bodies.
Specifications[]
Construction is of aluminum. Cars are 20 meters long, 2.8 meters wide and 4.086 meters high. All 203 series sets use a thyristor chopper-based traction system which makes a low hum as the train accelerates from idle.
