The 01A03, 01A04 and the 02A01 train (formerly known as AC01 and AC02) are current rolling stocks used on the Line 1 and Line 2 of Shanghai Metro. [4] They are built by Adtranz, Siemens Mobility and CSR Zhuzhou Locomotive, with modified by Shentong Metro between 2023 and 2024.

Contents

The contract was for a total of 216 cars (36 sets) initially, with an additional order of 12 cars (2 sets) in 2001. They are divided into two types of stock, AC01 for the Line 1, and AC02 for the Line 2.

Before the delivery of AC03, AC01 and AC02 trains were also assigned to the services of Line 3. [5]

Features

AC01 trains have livery in red and white and AC02 trains have livery in green and white. 01A03, 01A04 and 02A01's original cars are using the pneumatic doors and installed five-color indicators. 01A04's expansion cars are using the electric doors. 02A01s have no PIS (Passenger Information System) inside. [6]

Every carriage's lampshades were changed from grids to white plastic boards during the second general overhaul.

Formation

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. [7]

Expansion

Since 2006, CSR Zhuzhou Locomotive expanded AC01 and AC02 trains. 8 AC01 trains (118–125) and 16 AC02 trains (201–216) each expanded 2 additional cars. These cars were from another 12 sets (126–129 and 217–224). During the expansion, all carriages' traction systems were changed from GTO-VVVF to IGBT-VVVF. These AC01 trains renamed AC01A and AC02 trains renamed AC02A. [6]

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. [8]

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. [9] 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 wrecked carriages, 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. [10]

Incidents

Accident

Cars 98033 and 98042 wrecked on December 22, 2009, at the Shanghai Railway Station station. [9] 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 train maintenance worker training. [11]

Mishap

On July 15, 2018, set 133 was 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 signal equipment, causing delays for all northbound trains on Line 1. [12] Eventually, This set required an extensive repair and returned to service almost three years later on July 28, 2021.

Modifications

01A03

Between 2023 and 2024, all 01A03s were modified at Fujin Road Yard and Meilong Depot. Every car's doors were replaced with electric doors from the pneumatic doors used before. [13]

02A01

Cars 00071–00121, 01262 and 01273 were taken out of service since 2023 for signalling upgrading and replacing pneumatic doors to electric doors. They are the first to be modernized and backed to service in December 2023. [14]

The rest 02A01s were getting modified and backed to service gradually since January 2024.
