Refurbishment

In December 2012, set 05-114 underwent "type B" refurbishment, with a number of improvements utilizing features on the newer 15000 series sets.^[5] 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.^[5] 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.^[6]

All Tokyo Metro trains, including the Tokyo Metro 05 series in Indonesia, are planned to be retrofitted or refurbished by INKA soon.^[7][8][9] 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).

Retirement

The 05 series begun to be replaced by new 15000 series trains from May 2010. The first batch was replaced by the 15000 series, and has since been scrapped.

Eight former 05 series sets have been shipped to KAI Commuter (formerly known as KA Commuter Jabodetabek / KRL Jabodetabek) in Jakarta, Indonesia. They are sets 05-102, 05-104, 05-105, 05-107, 05-108, 05–109, 05-110 and 05–112. These sets have been reduced to eight cars.^[10]

Set 05-107 was withdrawn following derailment accident damage sustained in October 2012.^[10] Sets 05-102, 104, 105, 109 and 112 are no longer in operation and stored in Depok railway depot.^{[citation needed]} Set 05-110F is bearing the latest KAI Commuter's gray-red-white color scheme.
