Between July 2006 and September 2009, eight AC05 trains were temporarily assigned to Line 2 service, due to the shortage of AC02 trains, the delayed delivery of AC08 trains and the opening of Line 2 extension.^[2] In 2014, AC05 trains renamed 04A01 trains.^[3]

Overview

The AC05 trains have livery in purple and white, with the number "4" on every car, to help passengers distinguish the AC03 trains at Line 3 section.

In March 2002, Siemens Mobility and CSR Zhuzhou Locomotive awarded the contract to build AC05 trains for the Pearl line Phase 2 project. The first train built by CSR Zhuzhou Locomotive was completed on 18 December 2004.^[4][5]

Signaling upgrade

Between 2023 and 2025, all 04A01s were modified by Shentong Metro. They are undergoing TACS (DTO/GoA3) installation and every car's indicators increased from two to four. 04A01s' have also received new LCD screen displays. The LED display's color was changed from orange to red.^[6]
