MTR A-Stock EMU
Encyclopedia
The A-Stock is an Electric Multiple Unit
that operates on the MTR
rapid transit
railway system in Hong Kong
. There are two variants, one used on the conventional Tung Chung Line, and a more luxurious version used on the Airport Express
. The vehicle interiors were designed for MTR by Jones Garrard, while the vehicle exterior and driver's cab interior were designed by Design Triangle
. These two variations are built jointly by Adtranz
(acquired by Bombardier Transportation
in 2001) and Construcciones y Auxiliar de Ferrocarriles
and manufactured in Spain
in 1996-7.
was opened. TCL trains are capable of running with 8 cars in total. The total amount of cars ordered was 96.
The configuration of a TCL A Stock train is (Up track direction) V-W-X-Y-W-X-Z-V. Maximum train speed of is 135 km/h but with the Max. speed 130km/h on service currently, maximum acceleration
is 1 m/s² (3.6 km/h/s, or 2.25 MPHPS), maximum service brake rate is 1.1 m/s² (3.96 km/h/s, or 2.475 MPHPS), emergency brake has deceleration of 1.35 m/s² (4.86 km/h/s, or 3.04 MPHPS). Traction system of TCL trains is VVVF Inverter based on gate turn off thyristor
(GTO thyristor) technology.
(AEL) are made up of 7 cars up until 2003 although they can be run with 10 cars per train. The 88 cars were build and assembled by CAF
in Spain
while Adtranz
contributed control and traction equipment. 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.
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 doors on each side and 1 wheelchair space. Each passenger car is mounted with 2 LCD monitors at each end for broadcasting entertainment or turistic programmes and next-station announcement.
Maximum speed of AEL trains is 135 km/h, maximum acceleration
is 1 m/s² (3.6 km/h/s, or 2.25 MPHPS), maximum service deceleration is 1.1 m/s² (3.96 km/h/s, or 2.475 MPHPS), emergency brake can deliver deceleration of 1.35 m/s² (4.86 km/h/s, or 3.04 MPHPS). Traction of AEL trains are VVVF Inverter based on GTO Thyrsitor
technology.
Electric multiple unit
An electric multiple unit or EMU is a multiple unit train consisting of self-propelled carriages, using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages...
