MTR Metro Cammell EMU (DC)
The M-Train is the oldest variation of electric multiple unit that operates on the MTR rapid transit railway system in Hong Kong. 762 cars were ordered, built by Metro Cammell (now Alstom Transportation), and were refurbished starting in 1998 by the Australian company United Goninan.
Features
The M-Train is the one variation (apart from ex-KCR stock) that uses sliding doors (another variation is the C-Train), as opposed to others which use plug doors. They are currently operating on the Kwun Tong Line, Tsuen Wan Line, Island Line and the Tseung Kwan O Line.
The refurbishment process involved altering the fibreglass facade on the exterior ends to modernise their appearance, as well as the installation of the advanced digital voice announcement (DVA) and passenger information systems. United Goninan was subsequently awarded a contract to maintain the MTR rolling-stock. It is also interesting to note that such advances were not integrated into the M-Stock until late 2001.
