# Tokyo Metro 05 series

The TRTA/Tokyo Metro 05 series (営団・東京メトロ05系, Eidan/Tōkyō Metoro 05-kei) is an electric multiple unit (EMU) train type operated on the Tokyo Metro Tozai Line and Tokyo Metro Chiyoda Line Ayase Branch in Japan by the subway operator Tokyo Metro. Some sets have also been shipped to Indonesia, where they operate on the KRL Commuterline system in Jakarta.
A total of 43 ten-car trainsets were built from 1988 to 2004, with a number of variants. Sets 05-125 onward have a redesigned front end, and are called "05N series". Sets 05-114 to 05-118 have wide doors. A further four sets were due to be built, but the plan was changed to use 07 series trains transferred from the Yurakucho Line, so no further 05 series trains were built.

## Refurbishment

In December 2012, set 05-114 underwent "type B" refurbishment, with a number of improvements utilizing features on the newer 15000 series sets. The traction motors were replaced with new PMSM (permanent magnet synchronous motors), as used on the Chiyoda Line 16000 series sets, and internally, 17-inch (432 mm) LCD passenger information screens were added above the doorways. The same was done to fifth-batch sets 05-115 to 05-118 over the next few years, and eventually all sixth-batch sets 05-119 to 05-121 by the end of May 2020.
All Tokyo Metro trains, including the Tokyo Metro 05 series in Indonesia, are planned to be retrofitted or refurbished by INKA soon. The refurbishment or retrofit process including conversion from 4-Quadrant Chopper to IGBT-VVVF and changing the number of cars per trainset (8 cars to 12 cars per trainset).
