Tokyo Metro 6000 series

The Tokyo Metro 6000 series (東京メトロ6000系) was an electric multiple unit (EMU) train type operated by the Tokyo subway operator Tokyo Metro on the Tokyo Metro Chiyoda Line in Tokyo, Japan from 1971 to 2018. A number of trainsets have been exported to Indonesia for use by Kereta Commuter Indonesia following their withdrawal in Japan.

The trains have 20 m aluminium 4-door cars, and are used on the Chiyoda Line, as well as Odakyu Odawara Line, and Joban Line (all-stations "local" services). The sole three-car set was used on the Chiyoda Line Kita-Ayase branch line.

History
The TRTA 6000 series won the 1972 Laurel Prize from the Japan Railfan Club.

Refurbishment
The fleet was retro-fitted with air conditioning between 1988 and 1994. The fleet then underwent a programme of refurbishment between 1988 and 2007.

Retirement
The 6000 series trains have been in service since 1971, and have begun to show their age. In the 2010's, Tokyo Metro thought the 6000 series were becoming unreliable. As of 2018, they have been replaced by the 16000 series.

Resale to Indonesia


A number of 6000 series sets have been shipped to Kereta Commuter Indonesia in Jakarta, Indonesia, as listed below.

VVVF refurbished sets were shipped to Indonesia from 2016, with the first three sets arriving at the Port of Tanjung Priok in Jakarta on 29 July 2016.

The earlier chopper-controlled sets run as eight-car formations, while the refurbished VVVF-controlled sets operate as ten-car formations. However, some sets are shortened to make it easier for repairs.

Training set
The three-car prototype set 6000, used on the Kita-Ayase branch line until 2014, is used as a staff training unit at Shin-Kiba Depot in Koto, Tokyo.

The individual set histories are as shown below.

Related development
Both the Tokyo Metro 7000 series and the Tokyo Metro 8000 series were based on the 6000 series for the Yurakucho Line, Fukutoshin Line, and the Hanzomon Line. The cab car was inspired by Bay Area Rapid Transit (BART) in the San Francisco Bay Area, thus created the A-cars as the end cars only.
