Shanghai Metro AC05

The Shanghai Metro AC05, renamed 04A01 in 2014, is an electric multiple unit used on Line 4 of Shanghai Metro. It was developed by Siemens Mobility and built by CSR Zhuzhou Locomotive, and it entered service on 31 December 2005. In March 2002 Siemens Mobility and CSR Zhuzhou Locomotive were awarded the contract to build the trains for phase 2 of the Pearl line, and the first train built by CSR Zhuzhou was completed on 18 December 2004. The trains wear a purple and white livery with the number 4 on every car, which helps passengers tell them apart from the AC03 trains on the Line 3 section. Between July 2006 and September 2009 eight AC05 trains were temporarily assigned to Line 2 because of a shortage of AC02 trains, the delayed delivery of AC08 trains and the opening of the Line 2 extension. Between 2023 and 2025 all of them were modified by Shentong Metro, with TACS (DTO/GoA3) signalling installed, every car's indicators increased from two to four and new LCD screen displays fitted.
