The A1 (also 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 Depot.
Since 29 December 2002, A1 trains were assigned for service of Line 2 until the A2 trains delivered.
History
[edit]On 16 November 1993, the Siemens Mobility awarded the contract to build the rolling stock for the Line 1 of Guangzhou Metro. The first train was delivered on 9 April 1997, entering service on 28 June 1997, with the final train delivered on 15 March 1999.[5]
Details
[edit]The design of the A1 is identical to the AC01 and AC02, which are in operation in Shanghai Metro. A1 trains have livery in yellow and red. The train length is about 140m, with car height is 3.8m and width is 3m. The Tcp cars (Trailer car with cab and pantograph) have halogen headlights and every car have five-color indicators originally.[6]
Modernization
[edit]First overhaul
[edit]In 2008, A1 trains underwent an overhaul. Set 1x01-02 was the first to be overhauled and backed to service.[7][8] This set's doors were also converted to electric doors.
Refurbishment
[edit]The entire fleet was refurbished within a period of three years between 2021 and 2024.[9] The first refurbished train put into service on 30 May 2022.[10]
