User:Lekvwa/Shanghai Metro DC01

The 01A01 and the 01A02 train (formerly DC01) is a current trains stock used on the Line 1 of Shanghai Metro. They were manufactured by Adtranz and Simens Mobility, with first delivery in 1992. These cars were numbered 92011–92241 93011-93481 and 94011-94241 (trainset 101-116). All train sets were put into service in 1995.

Cars 93382-93473 and 940222-94233 (trainset 111-116) were used for expand trains 101 and 103-110 in 2008-2009. Therefore, cars 014352-014643 were manufactured by CSR Zhuzhou Locomotive used for expand trainset 111-116. Another three cars (92113, 14652 and 14663) were built for expanding trainset 102.

Features
DC01 trains are painted in red and white. 01A01s' door indicators were replaced by LEDs instead of halogen lamps, the five-color indicators and grid lampshades are retained after expansion. All carriages have installed red LED scrolling displays to show the next station.

01A02s' are that the carriage lampshades are replaced by white plastic boards instead of grids, the original destination signs are replaced by LED displays.All pneumatic doors were converted into electric doors. Five-color indicators are removed and all carriages have installed yellow LED scrolling displays to show the next station.

In the summer of 2006 after poor cooling affected 16 DC01 trains on Line 1, high temperatures inside the carriages had long been a problem, 96 ice cubes have been put into a one-meter-high waste container to alleviate the high temperature of the 96 carriages. In order to make up for the defects in the refrigeration power and design of carriage, emergency measures must be taken whenever the temperature reaches 33 °C (91 °F) or more. With the transformation between 2006 and 2008 from 6 cars to 8 cars, the air conditioners were improved and modernized, making ice waste containers a thing of the past.

Incidents
Car 92113 was wrecked on March 24, 2004 at the Tonghe Xincun station. 92113 was hit by car 99251. In 2007 it was stripped for removing parts, mothballed and replaced by the new carriage built by CSR Zhuzhou Locomotive.

Retirement
After the second general overhaul for 01A01 trains, numerous structural failures and cracks were found in these carriages in 2016. 80 carriages needed to be re-paired to repair and maintain service. At last, 8 cars (93131, 93162, 93293-93333, 93402 and 93413 ) were too faulty and used as spare parts sources.

Since the delivery of the 01A07 trains, demand for the 01A01s drastically lowered. By middle 2020, 01A01 trains were no longer formally assigned for revenue service, becoming a reserve fleet, 16 cars (92011-92033, 92102, 93121, 93133, 93162, 93233, 93262, 93273, 93293-93333, 93402, 93413, 93442, 93453, 94102-94121, 14652 and 14663) were taken out of service same year. 24 cars removed from service since 2023: 92131-92241, 94022, 94033, 94202 and 94213.

Newer 92113, 93191-93222, 93361, 94142 and 94153 are the first cars to be retired in July 2023. Newer 92113 was withdrawn from service due to a very poor condition. 93191's odometer shows 3,000,456 km, reached the end of its life. Therefore, Shentong Metro decommissioned 93191. It was donated to Shanghai University of Engineering Science in October 2023. 92113, 93202-93222, 93361, 94142 and 94153 are also written off and stored in Fujin Road Yard.

The rest cars (92043-92093, 92121, 93011-93061, 93142, 93153, 93173, 93181, 93251, 93282, 93342, 93353, 93462, 93473, 94042, 94053, 94071-94093, 94162, 94173, 94222 and 94233) of 01A01s were withdrew from service on June 5, 2024.

Refurbishment
As the original carriages of 01A02s are about to reached the end of their life, a refurbishment will be carried out. Renovation includes structural repairs, extend their lifespans for an additional 14 years. Work is expected to be completed by November 2025. Trains will be removed and transported to CRRC Zhuzhou Locomotive for renovation and rebuilt.
