The 03A01 trainset, previously known as AC03, serves as the rolling stock for Shanghai Metro's Line 3. This fleet was designed by Alstom and produced by CSR Nanjing Puzhen. Alstom secured the contract on 11 May 1999, with the initial train delivered on 5 December 2001 and commencing operation on 5 November 2002.
In 2014, the series was renamed from AC03 to 03A01. These trains are constructed with aluminum alloy car bodies, feature electrically operated doors, and have a top speed of 80 km/h. The original traction systems utilized Alstom ONIX IGBT-VVVF technology, while the refurbished units have been upgraded to incorporate Alstom OptONIX MG and Zhuzhou CRRC Times Electric tPower-TN28 systems.
Out of the total 168 units manufactured, 114 remain active in service as of now, with the remainder undergoing refurbishment scheduled from 2023 through to 2025. Shentong Metro Group operates these trains on Line 3, supported by depots located at North Jiangyang Road and Shilong Road Yard. The fleet is equipped with advanced safety solutions such as Alstom SACEM, with future plans to implement CASCO Tranavi Qiji technology to enable automated train operations.
Features
The AC03 series is characterized by a livery combining red, black, and white colors. Following the introduction of Line 4, each car's exterior was updated by adding the number "3" and a yellow stripe to assist passengers in differentiating AC05 trains running between Baoshan Road station and Hongqiao Road station, which are assigned to Line 4 service.
Refurbishment
CRRC Nanjing Puzhen is managing a comprehensive refurbishment program for the 03A01 fleet under contract PM216. This modernization involves applying a fresh livery featuring red, yellow, and white hues on both train bodies and fronts. Additionally, all vehicles will be fitted with modern passenger information systems equipped with LCD screens. The signalling will be upgraded from ATO to DTO (TACS), while traction equipment will shift from ONIX 1500 to OptONIX MG 1500 during the first phase affecting six cars (03371–03421). This extensive overhaul is designed to extend the service life of these trains from an initial 35 years to a minimum of 50 years, improving both reliability and operational durability.
