MTR K-Train

"K-Train" (alternatively K-Stock) is a colloquial name used to describe the Rotem EMU, a set of commuter electric multiple units operated by the MTR Corporation on the Tseung Kwan O and Tung Chung Lines of the Hong Kong Mass Transit Railway since April 2002.
==History==
The K-Train was designed for service on the Tseung Kwan O Line, intended to enter service in 2002. The sets were built by a consortium between Rotem (now Hyundai Rotem) and Mitsubishi Heavy Industries in Changwon, South Korea from 2002 to 2007. Initially, thirteen sets were ordered under contract TKE-C651; while intended to serve on the Tseung Kwan O Line incompatible signaling equipment meant that the sets could not run on the line and as a result were moved to the Kwun Tong Line as a stopgap measure.
When the sets entered service they were criticized due to delays and other safety issues such as passengers being injured by the doors; to combat this, MTR Corporation would "minimize the number of Korean trains for passenger service until a higher reliability of the systems concerned is achieved". Four additional sets were ordered for the Tung Chung Line in 2006, under contract TKE-C6522-04E, in anticipation of a projected passenger demand increase on the line. These entered service on 12 June 2006 and are virtually identical to the sets used on the Kwun Tong Line. With the extension of the Tseung Kwan O Line to LOHAS Park Station, all thirteen sets on the Kwun Tong line were moved back to the Tseung Kwan O Line, where they continue to serve.
A total of thirteen sets, numbered A301~A302 through A325~A326, are in service on the Tseung Kwan O Line, while four sets, V613~V813 through V616~V816, are in service on the Tung Chung Line; the fleet numbers of the Tung Chung Line K-Trains continue on from the CAF-Trains also used in service on that line. When not in use, the Tseung Kwan O Line sets are berthed at Tseung Kwan O depot and the Tung Chung Line sets at Siu Ho Wan depot.
==Design==
The K-Trains feature a semi-streamlined design. Two variants were produced under contracts TKE-C651 and TKE-C6522-04E used on the Tseung Kwan O and Tung Chung Lines respectively; both are similar to each other in appearance.
==Specifications==
Construction of the sets is of stainless steel. The sets use Mitsubishi's MAP-214-15VD143 2-level IGBT variable frequency drives, powering Mitsubishi MB-5086-A traction motors.
The Tung Chung Line sets are significantly more powerful than the Tseung Kwan O Line sets, using MB-5116-A traction motors as opposed to MB-5086-A traction motors on the Tseung Kwan O Line sets. The Tung Chung Line sets ride on Bombardier FLEXX Metro 3000 bogies while the Tseung Kwan O Line sets ride on Adtranz MetroStar bogies.
