The A1 series trains, constructed by Adtranz and Siemens Mobility between 1996 and 1997, operate on Guangzhou Metro's Line 1. These Class A electric multiple units (EMUs) accommodate up to 310 passengers per car and are built with aluminum alloy bodies. Originally equipped with pneumatic doors, these were later upgraded to electric systems during refurbishment. The fleet, consisting of 126 cars, continues to be actively operated by Guangzhou Metro Group and is maintained at the Xilang Depot.
Between 2021 and 2024, the entire train set is being modernized at the Dazhou Stabling Yard by CRRC Zhuzhou Locomotive. This upgrade includes the installation of advanced traction components such as Zhuzhou CRRC Times Electric’s IGBT-VVVF inverters alongside permanent-magnet synchronous motors, aimed at boosting energy efficiency and overall performance.
A noteworthy event occurred on 29 December 2002 when the A1 trains were temporarily assigned to Line 2 service until they were succeeded by newer A2 and later A4 train models, demonstrating Guangzhou Metro’s adaptability in fleet deployment.
History
On 16 November 1993, Siemens Mobility secured the contract to supply rolling stock for Guangzhou Metro’s Line 1. The initial trainset was delivered on 9 April 1997 and commenced operation on 28 June 1997. The final unit was handed over on 15 March 1999.
Details
The design of the A1 trains closely resembles the AC01 and AC02 models used on Shanghai Metro. Their exterior features a simple yellow paint scheme with a red stripe running along the car bodies. Each train measures roughly 140 meters in length, with a height of 3.8 meters and a width of 3 meters per car. Trailer cars equipped with cabs and pantographs (Tcp) are fitted with halogen headlights; initially, every car displayed five-color indicator lights.

Initial overhaul
The first comprehensive refurbishment of the A1 trains took place in 2008. The set numbered 1x01-02 led this process, returning to service with doors converted from pneumatic to electric operation.
Refurbishment
From 2021 through 2024, the entire fleet has been progressively upgraded. The inaugural modernized train resumed service on 30 May 2022, marking a significant advancement in extending both the service life and operational capabilities of these units.
