Tokyo Metro 7000 series

The Tokyo Metro 7000 series (東京メトロ7000系) is an electric multiple unit (EMU) train type operated by the Tokyo subway operator Tokyo Metro in Tokyo, Japan, between 1974 and 2022, and by KAI Commuter in Jakarta, Indonesia, since 2010. The design is based on the earlier Tokyo Metro 6000 series trains used on the Tokyo Metro Chiyoda Line.

History
The 7000 series was introduced into service on 30 October 1974, when the Yurakucho Line first opened. Its design is derived from that of the 6000 series developed for the Chiyoda Line. They were initially formed as five-car sets, but after the Yurakucho Line was extended to Chikatetsu-narimasu in 1983, the 7000 series sets were formed as ten-car sets. By 1989, 340 vehicles were built, which were formed into 34 ten-car sets.

Refurbishment
Between 2007 and 2009, the 7000 series fleet was refurbished coinciding with use on Fukutoshin Line services. The sets were fitted with new driver's cabs, CCTV equipment, updated traction and braking systems, automatic train operation, and other miscellaneous technical improvements. Some sets were also shortened to eight cars. The sets were also reliveried with brown, gold, and white stripes coinciding with use on Fukutoshin Line services. They originally sported a yellow bodyside line when used primarily on Yurakucho Line services.

Withdrawal
After the refurbishment programme, a significant portion of the 7000 series fleet was withdrawn; four of these sets were shipped to Indonesia in 2010.

In 2020, Tokyo Metro unveiled the 17000 series, which replaced the remaining 7000 series sets by April 2022.

Overseas operations
Four 7000 series ten-car sets (7117, 7121, 7122, and 7123) were shipped to Indonesia in 2010 for use on suburban services operated by KAI Commuter (formerly "KA Commuter Jabodetabek" or "KRL Jabodetabek") in Jakarta. The four sets were reduced to eight-car formations and are formed as follows, based at Depok Depot.

The two M1 cars in each set are equipped with two pantographs.

Accidents and incidents
2013 Bintaro train crash: On 9 December 2013, set 7121 (KRL 1131) collided with a Pertamina fuel truck at a level crossing at the Bintaro Permai intersection on the Rangkasbitung Line near Bintaro, South Tangerang, Indonesia, leading to 7 deaths and 45 injuries. The front two carriages of set 7121 as well as the tank truck were both destroyed in the ensuing fire. Set 7121 was retired and scrapped in December 2014.
