Shanghai Metro AC17

The 02A03 and the 02A04, formerly known as AC17, are a class of electric multiple unit currently used on Line 2 of Shanghai Metro. It was introduced into service in 2010 with the west and east extension of Line 2, and a total of 256 cars were built by Alstom and CSR Nanjing Puzhen. In 2014 AC17A was renamed 02A03 and AC17B was renamed 02A04. AC17 trains are divided into two types, AC17A and AC17B, whose designs are identical to the AC13 trains used on Line 10, with a livery in green, white and black. By 19 April 2019 the AC17B were assigned to the east extension only, from Guanglan Road station to Pudong International Airport station. The AC17B were formed as Tc-Mp+Mp-Tc when they entered service, and a contract for 64 additional cars to expand 16 02A04 sets was awarded to CRRC Nanjing Puzhen in December 2016; between 2018 and 2020 all 02A04 sets were removed and sent for expansion, each set gaining four cars. In 2023 the signalling of both types was upgraded from ATO to DTO (CBTC).
