205 series

The 205 series is a Japanese commuter electric multiple unit operated by the Japanese National Railways and its successor companies since July 1985 as well as in other countries.
==History==
The 205 series was designed in 1982 as a cheap-to-produce train that could complement the 201 series sets which were considered to be expensive to produce due to the latter's thyristor chopper-controlled traction systems. The first set entered service on the Yamanote Line on 15 July 1985, and has remained a staple of the JR fleet network ever since.
The 205 series is currently used on both JR East, JR West lines and Fujikyuko Line. A number of cars have been exported to Indonesia for use on the KRL Jabodetabek (now KAI Commuter) system.
== Design==
The 205 series uses a traditional design with an unpainted stainless steel body very much like most trains of the period. Each set has a different color scheme to indicate which area the sets serve. In KAI Commuter sets, the colors are similarized, where it using the red-white-yellow livery, and then gray-red-white livery, where it initiated from the 205-46 (ex-M4/Hae3) set.

;Cab design variations
There are four cab design variations of the 209 series. One is used for the 205-0 series sets (shared with the 205-5000 series sets and 205-600 series set Y12), another is used for the 205-500 series sets, a third is used for the 205-1100 series sets (shared with the 205-1200 and 209-3000 series sets) and the last is used on the 209-600 series sets.

==Specifications==
Construction is of stainless steel. Cars are 20 meters long and 2.8 meters wide. The 205 series were originally built with resistor-controlled traction systems, as they were cheaper to produce than thyristor chopper-controlled motors or something similar to that, but this was somewhat dated technology due to the advent of the variable frequency drive. The 205-5000 series are fitted with two-level insulated gate bipolar transistor variable frequency drives as a traction system which produce a distinctive, high-pitched whine.
==Export to Indonesia==
The historical 205 series sets, the 9+32 (ex-M22/M23), were once used in Yogyakarta Line from 2020, along with the soft launching of KAI Commuter Yogyakarta Line. This intended to overcome the shortage of KfW i9000 sets where the KfW sets are still refurbished in INKA. Starting in September 2022, the JR 205 9+32 are ending its operation in Yogyakarta, and currently operated for KAI Commuter Bogor Line as on 2023. The set JR 205-32, are using the Batik Parang Barong, which were removed once returned to Jakarta.
