The 02A03 and the 02A04 (formerly known as AC17) 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 256 cars were built by Alstom and CSR Nanjing Puzhen.

In 2014, AC17A was renamed as 02A03 and AC17B was renamed as 02A04.[1]

Overview

AC17 trains are divided into two types of stock, AC17A and AC17B. Their designs are identical to the AC13 trains, which are used on Line 10. They have livery in green, white and black.

By 19 April, 2019, AC17Bs were assigned for the service of east extension (Guanglan Road station – Pudong International Airport station) only.[2]

Formation of AC17B

The AC17Bs were formed as Tc-Mp+Mp-Tc as they entered service. An additional contract of 64 cars for expand 16 02A04 sets was awarded to CRRC Nanjing Puzhen in December 2016, to increase the capacity of Line 2.

Between 2018 and 2020, all 02A04s were gradually removed and transported to CRRC Nanjing Puzhen for expansion. Each set added four cars. Every 02A04 car added ceiling level displays during the expansion work.[3]

Signaling upgrade

In 2023, 02A03s and 02A04s‘ signalling system were upgraded from ATO (TBTC) to DTO (CBTC).[4]
