Four variations of the MTR rolling stock operate on the MTR Network of Hong Kong . All trains are Electric Multiple Unit s (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 Fan s 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). ROLLING STOCK OF KWUN TONG LINE, TSUEN WAN LINE, ISLAND LINE, TSEUNG KWAN O LINE AND DISNEYLAND RESORT LINE 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:
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:
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). ''' train parking at the Sunny Bay Station .]] Please note that 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:
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 Wheelchair s. K-Stock ''']] K-Stocks came into service for MTR in August 2002. They are built by Mitsubishi 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 '''. K-Stock trains have 3 types of cars:
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 . ROLLING STOCK OF THE TUNG CHUNG LINE ''' train.]] 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. Cars of TCL trains can be divided into 5 types:
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. ROLLING STOCK OF THE AIRPORT EXPRESS Trains of Airport Express Line (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. The AEL train cars can be divided into 6 types:
Configuration of an AEL train is E-F-G-H-F-G-J-K. Except for K cars that have 5 doors on each side, all other cars in AEL have 2 door each side. 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. |
