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.

[edit] Features
The M-Train is the only variation (apart from ex-KCR stock) that uses sliding doors, 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.
Each car is 3000 mm width over body panel, floor to rail is 1100 mm high and roof to rail is 3700 mm high.
A service train has an acceleration of 1.0 m/s2 (3.6 km/h/s, or 2.25 MPHPS), service brake is regenerative blend with air brake at the rate of 1.0 m/s² (3.6 km/h/s, or 2.25 MPHPS) and emergency brake is air-brake at 1.4 m/s2 (5.04 km/h/s, or 3.15 MPHPS). The maximum speed for the M-Stock is 80 km/h, and are fitted for driverless operation. Primary suspension is chevron springs, while the secondary suspension is air bags. Traction system is through GTO chopper control. Each car has 45 seats and capable of holding 268 standing passengers, with space for wheelchairs.
[edit] Variants
M-Train is divided into 6 types of stock. They are the:
- M-Stock - Modified Initial System stock (A/C101-170,B/C401-435)
- T-Stock - Tsuen Wan Line Stock A/C171-247 (except A/C182), B/C436-479 (except B/C459)
- I-Stock - Island Line Stock( A/C248-256,B/C459)
- G-Stock - Trains for Eastern Harbour Tunnel extension (A/C182,A/C257-269,B/C480-485)
- H-Stock - Trains For the signalling Upgrade (A/C270-291,B/C486-496)
- Q-Stock - All D Cars(See Below)(D601-788)
The Traction system of M-Stock and T-Stock trains were changed to Chopper from Cam Shaft in 1992-1995, so they are called CM-Stock and CT-Stock now. All G-Stock, Q-Stock and H-Stock trains belong to Kwun Tong Line, Tseung Kwan O Line and Disneyland Resort Line respectively.
The configuration of a M-train in revenue service is (Up track direction) A-C-D-C-B-D-C-A (in 8cars) or (Up track direction) A-C-C-A (4cars, unavailable now). There was once a type of trains with all motor A-C-C-B-C-B-C-A (also known as "solid train"), but it was ungrouped into Disneyland Resort Line trains. Units A/C274 A/C281 A/C284 A/C289 A/C291 and B/C490 have been assigned to the Disneyland Resort Line and completely refurbished into new trains (see below.)

The M-Stock trains (now CM-Stock trains) were the first batch of trains ordered by MTR. They were delivered from 1979 to 1982, and had their engines changed to GTO Chopper from Cam Shaft in 1992-1995. They serve on the Kwun Tong Line.
[edit] Phase 2A
The T-Stock trains (now CT-Stock trains) were the second batch of trains ordered by MTR. They were delivered from 1982-1985 and also had their engines changed to GTO Chopper in 1992-1995. They serve on the Tsuen Wan Line.
[edit] Phase 2B
The I-Stock trains were the third batch of trains, they were delivered from 1985-1986 and serve on the Island Line.

The G-Stock trains were built for the Eastern Harbour Crossing extension of the Kwun Tong Line (became part of the Tseung Kwan O Line in 2002), they were delivered from 1988-1989 and still serve on the Kwun Tong Line as well as the Tseung Kwan O line. They were the last batch of MTR M-Trains to be made by Metro Cammell before being acquired by GEC Alsthom (now Alstom) in 1989.
[edit] Phase 3

[edit] Disneyland Resort line stock
When Disneyland Resort Line opened in 2005, some Second-hand M-Train units were refurbished and assigned to the line. The MTR designed a new driverless train and produced it by refitting existing M-Trains for the line which is designed with a Disney theme in mind. Statues of well-known Disney characters are included inside of the trains, such as Mickey Mouse and Donald Duck.
Units A/C274 A/C281 A/C284 A/C289 A/C291 and B/C490 of M-Train have been assigned to the Disneyland Resort Line and completely refurbished into new trains as:
- P501- Q501 - Q502 - P502
- P503- Q503 - Q504 - P504
- P505- Q505 - Q506 - P506
Each car is 3000 mm width over body panel, floor to rail is 1100 mm high and roof to rail is 3700 mm high.
A service train has an acceleration of 1.0 m/s2 (3.6 km/h/s, or 2.25 MPHPS), service brake is regenerative blend with air brake at the rate of 1.0 m/s² (3.6 km/h/s, or 2.25 MPHPS) and emergency brake is air-brake at 1.4 m/s2 (5.04 km/h/s, or 3.15 MPHPS). The maximum speed for the M-Stock is 80 km/h, and are fitted for driverless operation. Primary suspension is chevron springs, while the secondary suspension is air bags. Traction system is through GTO chopper control.
