History

Set 6110 in 1985 before the retro-fitting of air-conditioning

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.^[4] The fleet then underwent a programme of refurbishment between 1988 and 2007.^[4]

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In the 2010's, Tokyo Metro thought the 6000 series were becoming unreliable.^{[citation needed]} As of 2018, they have been replaced by the 16000 series.

Resale to Indonesia

Set 6131 (with larger passenger windows) in Indonesia in December 2016

Set 6118 (with smaller passenger windows) operated by Kereta Commuter Indonesia at Kebayoran Station in October 2023

Withdrawn Tokyo Metro 6000 set 6112 in Cikaum

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.^[5]

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.^[6]

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.
