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. They are refurbished from 2021 to 2024 by CRRC Guangzhou Rail Transit Equipment in Dazhou Stabling Yard.

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.
