The Rotem EMU (also known as K-Train/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. 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 2018.
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.
The configuration of a TKOL K Stock train is (Eastbound) A-C-B-B-C-B-C-A (Westbound). Maximum train speed is 90 km/h (56 mph) but with the max speed of 80 km/h (50 mph) on service currently, maximum starting 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.
