The K-Stock is an electric multiple unit that operates on the MTR rapid transit railway system in Hong Kong.There are two variants: those delivered for the Tseung Kwan O Line now (but from 2002-2009 used on the Kwun Tong Line), and those delivered in 2006 to 2007 for the Tung Chung Line. In 2003 and 2004, these trains (Kwun Tong Line stock) ran on Tsuen Wan Line, Island Line and Tseung Kwan O Line.
Combination of vehicles
The first TKE-C651 entering service in late April 2002, the 104 cars were built by Mitsubishi Heavy Industries and Hyundai 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 were 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.
All K-Stock cars are 22,000 mm (72 ft 2.1 in) in length, 3,118 mm (10 ft 2.76 in) in width, 3,698 mm (12 ft 1.59 in) in height. Maximum speed of K-Stock is 80 km/h (50 mph), maximum acceleration is 1.3 m/s2 (4.27 ft/s2) (4.72 km/(h·s) or 2.93 mph/s), maximum service deceleration rate is 1.35 m/s2 (4.43 ft/s2) (4.86 km/(h·s) or 3.02 mph/s), emergency deceleration is 1.4 m/s2 (4.59 ft/s2) (5.04 km/(h·s) or 3.13 mph/s). This modern train is equipped with the modern 2-Level 3300V-1200A-IGBT (Insulated Gate Bipolar Transistor) VVVF Inverter from Mitsubishi Electric.
The first TKE-C6522-04E train came into service for MTR in 12 June 2006 to 26 February 2007. They were built by Mitsubishi Heavy Industries and the ROTEM consortium. Originally MTRC wanted to buy new additional trains for the Tung Chung Line when the North Island Line project begins. MTR anticipated that the opening of the Disneyland Resort and Ngong Ping 360 would have an increase in passenger demand and therefore ordered four new trains for Tung Chung Line. The time frame from order to completion is short in comparison to other stock, however; the four new trains can only be made to be identical to existing Tseung Kwan O Line K-Stock.
Maximum speed of K-Stock is 135 km/h (84 mph), maximum acceleration is 1.3 m/s2 (4.3 ft/s2) (4.72 km/(h·s) or 2.93 mph/s), maximum service deceleration rate is 1.35 m/s2 (4.4 ft/s2) (4.86 km/(h·s) or 3.02 mph/s), emergency deceleration is 1.4 m/s2 (4.6 ft/s2) (5.04 km/(h·s) or 3.13 mph/s). This advanced train is equipped with the modern 2-Level 3300V-1200A-IGBT VVVF Inverter from Mitsubishi Heavy Industries.
On 14 December 2012, MTR announced that the company will buy 37 sets of 9 cars train from Rotem for the future North–South Corridor and the train will be in service in 2015.[1]
