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


Technical details

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]


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

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]

<span class="mw-page-title-main">Tilting train</span> Type of train that can tilt in curves

A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks. As a train rounds a curve at speed, objects inside the train experience centrifugal force. This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest, and standing passengers to lose their balance. Tilting trains are designed to counteract this by tilting the carriages towards the inside of the curve, thus compensating for the g-force. The train may be constructed such that inertial forces cause the tilting, or it may have a computer-controlled powered mechanism.

Taebaek Line is a single-track electrified railway mainline connecting Jecheon station to Baeksan station in South Korea. At its two ends, the Taebaek Line connects to the Jungang Line and Yeongdong Line. The line was originally two spur lines, which were built across difficult mountainous terrain in stages, before a connection was built. The line includes the steepest section of the South Korean network, a short parallel line that is operated as a second track on the section includes South Korea's longest spiral tunnel. The centerpiece of the last-built section west of Taebaek, is a tunnel that was the longest in South Korea at the time of its construction, and Chujeon Station at the eastern end of the tunnel is the highest altitude in South Korea at 855 m (2,805 ft). In passenger traffic, the line is served by cross-country passenger trains connecting the capital Seoul with Korea's east coast. In freight traffic, while coal transport declined, the line carries significant cement transport. In the winter, regular special trains take tourists along the scenic route.

HSR-350x, alternatively called G7, KHST or NG-KTX, is a South Korean experimental high-speed train. It was developed and built in a joint project of government research institutes, universities and private companies that started in 1996, which aimed to reduce import dependence in high-speed rail technology. New components developed for the HSR-350x included motors, electronics, and the carbody of passenger cars. Test runs were conducted between 2002 and 2008. The experimental train achieved the South Korean rail speed record of 352.4 km/h (219.0 mph) in 2004. The HSR-350x was the basis for Korail's KTX-II (KTX-Sancheon) commercial high-speed trains.

The Gyeongbu high-speed railway, also known as Gyeongbu HSR, is South Korea's first high-speed rail line from Seoul to Busan. KTX high-speed trains operate three sections of the line: on April 1, 2004, the first between a junction near Geumcheon-gu Office station, Seoul and a junction at Daejeonjochajang station north of Daejeon, and a second between a junction at Okcheon station, southeast of Daejeon, and a junction near Jicheon station, north of Daegu entered service; then on November 1, 2010, the third section, between a junction west of Daegu and Busan became operational. The missing gaps across the urban areas of Daejeon and Daegu were in construction for an expected opening in 2014, separate tracks into Seoul Station were also planned. The temporary ends of the three sections were connected to the parallel conventional Gyeongbu Line by tracks that will serve as interconnector branches upon the completion of the entire line. On August 1, 2015, construction on urban areas of Daejeon and Daegu were completed; all the sections of HSR line were connected.

<span class="mw-page-title-main">Honam high-speed railway</span>

The Honam high-speed railway, also known as Honam HSR, is a high-speed rail between Osong and Mokpo in South Korea. The line is a part of Korail's Korea Train Express (KTX) system, accelerating Seoul–Mokpo and Seoul–Gwangju KTX high-speed services which currently use the existing conventional Honam Line. On April 1, 2015, the line was inaugurated by the South Korean President Park Geun-hye with the attendance of 1200 invited guests and members of the public at Gwangju Songjeong Station in Gwangju, the line's terminus. The line diverges from Osong station on the Gyeongbu high-speed railway, and stops at Gongju, Iksan, Jeongeup Stations. Journey times between Seoul and Gwangju has been cut from 2 h 40 min to just 90 min, making daily commuting possible. The Honam HSR is intended to bring business, and economic opportunities to the province of Jeollanam-do, which has seen slower development than other parts of South Korea. The line has been open to the public since April 2, 2015 for revenue service.

HEMU-430X is a South Korean high-speed train intended for a maximum speed of 430 km/h (267 mph). On March 31, 2013, it achieved 421.4 km/h (261.8 mph) in a test run, making South Korea the world's fourth country after France, Japan and China to develop a high-speed train running above 420 km/h (261 mph). The main new feature of the train compared to older South Korean high-speed trains is distributed traction. The commercial versions of the trains, tentatively named the EMU-260 and EMU-320, were delivered to Korail from 2020–2021.

High-speed rail service in South Korea began with the construction of a high-speed line from Seoul to Busan in 1992, and was inspired by Japan's Shinkansen. The first commercial high-speed rail service was launched on April 1, 2004. Currently, South Korea hosts two high-speed rail operators: Korea Train eXpress (KTX) and Super Rapid Train (SRT).
