Trains on the MTR
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 1432mm rail gauge and are powered by 1500V 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 (~23m), widest and highest capacity rolling stocks (~350), with the most number of cars on a train.
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 Transportations), and were refurbished in the mid-1990s 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.Which are:
- M-Stock - Modified Initial System stock (A/C101-170,B/C401-435)
- T-Stock - Tsuen Wan Extension Stock A/C171-247 (expect A/C182), B/C436-479 (expect 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 cars of the M-Train can be subdivided into four types as follows:
- A cars: cars with driver cab and motor, 22850mm in length. There are 191 M-Train A cars in the MTR system in 2003.
- B cars: cars with motor, 22000mm in length. There are 96 M-Train B cars in MTR in 2003.
- C cars: cars with motor and pantograph, 22000mm in length. There are 287 M-Train C-cars in MTR in 2003.
- D cars: trailers only, 23160mm in length. In 2003 MTR owns 188 M-Train D cars.
The configuration of a M-train in revenue service is A-C-D-B-C-D-C-A
Please note:A/C274 A/C281 A/C284 A/C289 A/C291 and B/C490 are restored to Disneyland Resort Line Train as
- P501- Q501 - Q502 - P502
- P503- Q503 - Q504 - P504
- P505- Q505 - Q506 - P506
Each car is 3000mm width over body panel, floor to rail is 1100mm high and roof to rail is 3700mm high.
The maximum speed for the M-Stock is 80km/h. 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.
K-Stocks come into service for MTR since August, 2002. They are built by Mitsubishi and ROTEM consortium. Originally these stocks are to be assigned on the Tseung Kwan O Line, but maintenance problems mean that they are now all assigned to Kwun Tong Line instead.
K-Stock trains have 3 types of cars:
- A cars: cars with driver cab and motor. In 2003 there are 26 K-Stock A cars in MTR system.
- B cars: cars with motor. In 2003 there are 39 K-Stock B cars in MTR system.
- C cars: cars with motor and pantograph. There are 39 K-Stock C cars in the MTR system in 2003.
Since it is much heavier than M-Stocks, it does not have any cars similar to D cars in M-Stocks. The configuration of a K-Stock train in revenue service is A-C-B-C-B-B-C-A.
All K-Stock cars are 22000mm in length, 3118mm in width, 3698mm in height.
Maximum speed of K-Stock is 80km/h, maximum acceleration is 1.3m/s/s, maximum service deceleration rate is 0.8~1.35m/s/s, emergency deceleration is 1.4m/s/s This modern train is equipped with the modern 4th generation IGBT (Insulated Gate Bipolar Transistor) VVVF converter from Hitachi.
Rolling Stock of the TCL
Trains of the Tung Chung Line are made up of 7 cars up until 2003, and was increased to 8 cars in 2004. 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 Transportations) and Construcciones y Auxiliar de Ferrocarriles and manufactured in Spain. TCL trains are capable of running with 10 cars in total. Cars of TCL trains can be divided into 5 types:
- V cars: cars with driver's cab, motor, pantograph. They are 24600mm in length, with 42 seats, 2 wheelchair spaces and can hold up to 252 standing passengers. In 2003 MTR corporation owns 24 V-cars.
