Trains on the MTR
From Wikipedia, the free encyclopedia
Four variations of the MTR rolling stock operate on the MTR Network of Hong Kong. All trains are electric multiple units (EMUs), equipped with ATC and ATP, operating on 1432 mm rail gauge and are powered by 1500 V DC through overhead electrification. Except the rolling stock of the Airport Express, all other trains are designed with features to cope with high density passenger traffic on stopping services. Examples are the latitudinal seating arrangement, additional ventilation fans and 5 doors on each side per car. MTR is the metro system in the world using the longest (~23 m), widest and highest capacity rolling stocks (~350 passengers/car), with the most cars making up a train (8 cars constitute 1 MTR EMU).

Tseung Kwan O and Disneyland Resort Lines
[edit] Modernization Train (M-Train)
The M-Train is the oldest variation of the rolling stock that operates on the MTR. They were built originally by Metro Cammell (now Alstom Transportation), and were refurbished starting in 1998 by the Australian company United Goninan. It is the only variation 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 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.
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 90's, so they are called CM-Stock and CT-Stock now.
-
- All G-Stock and H-Stock Trains Belong to Tseung Kwan O Line and Disneyland Resort Line.

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). 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 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, service brake is regenerative blend with air brake at the rate of 1.0 m/s² and emergency brake is air-brake at 1.4 m/s2. 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] K-Stock
K-Stocks came into service for MTR in late April 2002. They are built by Mitsubishi Heavy Industries and ROTEM consortium. Originally these trains are designated to serve on the Tseung Kwan O Line, but incompatible signalling apparatus installed in the new trains (running mode rather than the traditional automatic control system found in the M-stock) means that all of the K-stock trains are unable to serve on the Tseung Kwan O Line. As an alternative all of those prototypes are ordered to serve on the Kwun Tong Line.

Since it is much heavier than M-Train, it does not have any cars similar to D cars in M-Train. The configuration of a K-Stock train in revenue service is A-C-B-C-B-B-C-A.
All K-Stock cars are 22000 mm in length, 3118 mm in width, 3698 mm in height.
Maximum speed of K-Stock is 80 km/h, maximum acceleration is 1.3 m/s², maximum service deceleration rate is 0.8~1.35 m/s², emergency deceleration is 1.4 m/s² This modern train is equipped with the modern 2-Level 3300V-1200A-IGBT (Insulated Gate Bipolar Transistor) VVVF Inverter from Mitsubishi Heavy Industries.
[edit] Rolling stock of the Tung Chung Line
[edit] A Stock
Trains of the Tung Chung Line are made up of 7 cars up until 2003, and was increased to 8 cars in 2004 when the KCR West Rail was opened. Airport Express and Tung Chung Line uses trains that are dedicated specifically to their respective lines. These two variations are built jointly by Adtranz (now Bombardier Transportation) and Construcciones y Auxiliar de Ferrocarriles and manufactured in Spain. TCL trains are capable of running with 8 cars in total.

The configuration of a TCL train is (Up track direction) V-W-X-Y-W-X-Z-V. Maximum train speed of a TCL train is 135 km/h (the Max. speed on service is 130km/h currently), maximum acceleration is 1 m/s², maximum service brake rate is 1.1 m/s², emergency brake has deceleration of 1.35 m/s². Traction system of TCL trains is VVVF Inverter based on gate turn off thyristor (GTO thyristor) technology.
[edit] TCL-K Stock
The first TCL K-Stock train came into service for MTR in 12 June 2006. They are built by Mitsubishi Heavy Industries and ROTEM consortium. Originally MTRC wanted to buy new additional trains for Tung Chung Line when North Island Line project begins. MTR anticipated that the opening of Disneyland Resort and Ngong Ping 360 would have an increase in passenger demand, and therefore ordered 4 new trains for Tung Chung Line. Time frame from order to completion is short in comparison to other stock, however; the 4 new trains can only be made in the likeness of their Kwun Tong Line K-Stock counterparts, in the context of insufficient time.
K-Stock trains have 3 types of cars:
- V car, based on A car of K-Stock, totally 8 cars;
- W car and X car, based on B car, totally 12 cars;
- Y car and Z car, based on C car, totally 12 cars.
Maximum speed of K-Stock is 130 km/h, maximum acceleration is 1.3 m/s², maximum service deceleration rate is 0.8~1.35 m/s², emergency deceleration is 1.4 m/s². This advanced train is equipped with the modern 2-Level 3300V-1200A-IGBT VVVF Inverter from Mitsubishi Heavy Industries. Configuration is similar to Kwun Tong Line K-Stock as: V(A)-Z(C)-X(B)-Y(C)-W(B)-X(B)-Z(C)-V(A).

[edit] Rolling stock of the Airport Express
Trains of Airport Express (AEL) are made up of 7 cars up until 2003 although they can be running with 10 cars per train. The cars are Bombardier Transportation's Movia 456 Metro. To cope with extra traffic demand derived from the opening of AsiaWorld-Expo station, one more 'F' car had been added to each train to form a total of 8 cars.

Each seat is fitted with an on-board info-entertainment screen. Maximum speed of AEL trains is 135 km/h, maximum acceleration is 1 m/s², maximum service deceleration is 1.1 m/s², emergency brake can deliver deceleration of 1.35 m/s². Traction of AEL trains are VVVF Inverter based on GTO Thyrsitor technology.
