The 02A02 (formerly known as AC08) are current rolling stocks used on the Line 2 of Shanghai Metro. It was introduced into service in 2010 with the west and east extension of Line 2. A total of 168 cars were built by Alstom and CSR Nanjing Puzhen.
In 2014, AC08 was renamed as 02A02.[1]
Description
[edit]As a part of the west extension program of Line 2, AC08 was ordered at the same time as AC06, but both manufacturing and delivery have been delayed. Since the western extension opened in late 2006, eight AC05 trains have assigned to Line 2 service, until AC08 trains starting delivered between 2008 and 2009.[2]
AC08s have livery mainly in green and white. They are also equipped with upper window LED screens to provide passenger information for the first time.[3] The Alstom ONIX 1500 Variable Frequency (IGBT) inverters like the ones that use the Singapore’s North East Line Alstom Metropolis C751A trains.
Signaling upgrade
[edit]Between 2022 and 2023, 02A02s‘ signalling system were upgraded from ATO (TBTC) to DTO (CBTC).[4]
