Tilting Train Express (TTX) or Hanvit 200 is a South Korean experimental high-speed tilting train, which is currently being tested by the Korea Railroad Research Institute (KRRI).

Technical details[edit]

The six-car train has distributed power and a design speed of 200 km/h (124 mph) and a planned service speed of 180 km/h (112 mph).[1] The carbody is made on an aluminum honeycomb structure sandwiched between a carbon/epoxy composite material, reducing carbody mass by 40%.[1] The interior design of two of the powered cars provides for 29 First Class seats in 2+1 configuration, that of the other two powered cars 56 Standard Class seats in 2+2 configuration, that of unpowered end cars 54 Standard Class seats.[1]

History[edit]

TTX was presented to the public on January 16, 2007, when the first test run was planned for the next month.[2] The actual first test was conducted on April 2, 2007, on the Chungbuk Line.[3]

Following a call by Nam-Hee Chae, the president of the Korea Railroad Research Institute, for proposals for a generic name for Korean-made high-speed trains,[4] on April 5, 2007, Chae announced the name Hanvit (Hangul: 한빛),[5] which means a streak of intense light in Korean.[6] Under the new naming scheme, TTX became Hanvit 200.[5]

The first test run with active tilting was conducted in the presence of the media on May 22, 2007, between Osong Station and nearby Ogeunjang Station on the Chungbuk Line.[7] At the time, the train was planned to enter service in 2010.[7] Until December 21, 2008, the train ran over 20,000 km (12,000 mi) in test runs on the Chungbuk Line, short of the 100,000 km (62,000 mi) planned.[8] The test program of 100,000 km (62,000 mi) was completed until the end of 2009, with test runs on the Chungbuk, Jungang, Honam, Gyeongbu and Taebaek Lines followed by high-speed testing on the Gyeongbu High Speed Railway (Gyeongbu HSR), with 200 km/h (124 mph) achieved at 00:33 on November 19, 2009, between Osong and Daejeon.[9] In a further test in September 2010 on the not yet opened second stage of the line between Daegu and Busan, the train achieved 222 km/h (138 mph).[10]

Series version[edit]

By the end of 2009, the series version of the train was expected to enter regular service in 2013, starting on the Jungang Line.[9] The future service is expected to reduce the travel time between Cheongnyangni in Seoul and Yeongju from the current Mugunghwa-ho travel time of 3 hours 25 minutes to 2 hours 55 minutes, further reducing to 1 hour 55 minutes after the upgrade of the Jungang Line.[10] Further services are planned on the Taebaek and Yeongdong Lines.[9]
