Original sets
Like the DC01, The initial contract for Line1 and Line 2 was designed as 6-cars sets, for the lower expected ridership in 1990s and 2000s. Trains were formed as Tc-Mp-M+Mp-M-Tc.Expansion program
Since 2006, CSR Zhuzhou Locomotive expanded AC01 and AC02 trains. 8 AC01 trains (118–125) and 16 AC02 trains (201–216) each added 2 additional cars. These cars were from another 12 sets (126–129 and 217–224). These AC01 trains renamed AC01A and AC02 trains renamed AC02A. The second contract for CSR Zhuzhou Locomotive included 72 cars for expanding the remaining 12 trains. During the expansion, 8 AC02 trains (217–224) renumbered 130–137. All trains (126-129 and 130-137) renamed AC01B and assigned to Line 1 service together. Set 117 was the last to be expanded. Before the expansion project, this set involved in a crash at Shanghai Railway Station station on December 22, 2009, and was taken out of service. In 2011, the third contract awarded to CSR Zhuzhou Locomotive again, including 4 cars (98022, 98033, 14673 and 14682). 98022 and 98033 used for replacing two damaged cars with same numbers, 14673 and 14682 used for expanding the set. Set 117 was renamed AC01C separately.Post-expansion
In 2014, all four types of train renamed again. AC01A and AC01C renamed 01A03, AC01B renamed 01A04, AC02A renamed 02A01. In 2018 and 2019, some of the 01A03s and 02A01s were found several cracks on the frame during some scheduled inspections. These cars with structural defects were immediately being taken out of revenue service and Shentong Metro deployed emergency repairs by November 2019.Mishaps
On March 24, 2004, car 99251 hit car 92113 and damaged. It was repaired by Bombardier and returned to service later. Cars 98033 and 98042 wrecked on December 22, 2009, at the Shanghai Railway Station station. 98033 and 98042 were hit by car 013151. In 2011, they were stripped for removing parts and stored in the maintenance shop of Meilong Depot. They were replaced by the new carriages built by CSR Zhuzhou Locomotive. In 2015, car 98042 was converted into SMTC Experimental Car by CRRC Dalian R&D and used for rolling stock maintainer training. On July 15, 2018, set 133 was pulled out of service at North Zhongshan Road station due to the fault. While the train was moving to the Fujin Road Yard, a defective motor dropped on a wayside signal equipment, causing delays for all northbound trains on Line 1. Eventually, This set required an extensive repair and returned to service almost three years later on July 28, 2021.Modifications
