The 02A03 and 02A04 train models, previously known as AC17, operate on Shanghai Metro Line 2. These trains were introduced in 2010 in conjunction with the line’s west and east expansions. A total of 256 vehicles were manufactured through a collaboration between Alstom and CSR Nanjing Puzhen.
In 2014, the original AC17A and AC17B designations were revised to 02A03 and 02A04, respectively.
Overview
The AC17 series consists of two versions: AC17A and AC17B, both of which share the same design characteristics as the AC13 trains running on Line 10. Their exterior paint scheme incorporates green, white, and black hues.
As of April 19, 2019, the AC17B units have been allocated solely to the eastern extension segment stretching from Guanglan Road to Pudong International Airport stations. This deployment aligns with operational plans aimed at maximizing rolling stock efficiency along this busy route.
Formation of AC17B
AC17B trainsets operate in a Tc-Mp+Mp-Tc configuration. Under contract PM109, awarded to CRRC Nanjing Puzhen in December 2016, an additional 64 cars were produced to lengthen 16 sets of 02A04 trains on Line 2, thereby boosting passenger capacity.
From 2018 through 2020, all existing 02A04 trainsets were progressively sent back to CRRC Nanjing Puzhen for expansion. Each trainset was extended by adding four cars. Throughout this upgrade, ceiling-mounted display panels were installed in every newly added car within the 02A04 series.
Signaling upgrade
In 2023, both the 02A03 and 02A04 fleets received an upgrade to their signaling systems, transitioning from ATO (TBTC) technology to the more sophisticated DTO (CBTC) system. This enhancement improved both safety measures and operational performance.
