The A1 (commonly known as Guangzhou Metro Line 1 Trains) is a rolling stock built by the Adtranz and Siemens Mobility from 1996 to 1997 for the Line 1, with operation in Guangzhou Metro. [1] They are refurbished from 2021 to 2024 by CRRC Guangzhou Rail Transit Equipment in Dazhou Stabling Yard.

Contents

On 29 December 2002, A1 trains were assigned for service on Line 2 until the A2 trains were delivered, which in turn were replaced with A4 trains.

History

On 16 November 1993, Siemens Mobility was awarded the contract to build the rolling stock for Line 1 of Guangzhou Metro. The first train was delivered on 9 April 1997, entering service on 28 June 1997, and the final train delivered on 15 March 1999. [6]

Details

The design of the A1 is identical to the AC01 and AC02, which are in operation with the Shanghai Metro. A1 trains have a plain yellow livery with a red stripe running along the body. The train length is about 140m, with a car height of 3.8m and width of 3m. The Tcp cars (Trailer car with cab and pantograph) have halogen headlights and every car originally had five-color indicators. [7]

Modernization

First overhaul

In 2008, A1 trains underwent an overhaul. Set 1x01-02 was the first to be overhauled and returned back to service. [8] [9] This set's doors were also converted to electric doors.

Refurbishment

The entire fleet was refurbished within a period of three years between 2021 and 2024. [10] The first refurbished train was returned to service on 30 May 2022. [11]
