HSR-350x (한국형 고속철도, High-speed rail 350x), also known as Korean G-7, is the high speed train which was recently developed and created purely and independently by South Korea. The main motivation was to reduce traffic problem and to pull up the nation's science and technology to the level of world's top seven leaders known as the G-7 (Currently it is G-8, not G-7). This explains why HSR-350x is also known as "Korean G-7" or "G7" as a short form.

[edit] HSR-350x
KTX's (한국고속철도, Korean Train Express) South Korean engineers established this project in 1995, a couple of years before the arrival French TGV's technologies. This was the only survival route for Koreans to establish Korean's independent HSR technologies. Korean Rotem and National Rail Technology Institude of Korea have researched and developed this train for 10 years. As a proposal, HSR-350 was expected to run 350km/h (217mph) in regular basis, which is 50km/h faster than its rival, French TGV's commercial speed (300km/h, 186mph). Although TGV is the global dominating high-speed train, like Japanese Shinkansen, it doesn't incorporate some of the recent Korean technologies such as aluminum body, digital traffic control, and a pressure compensation system. Due to the KTX's complaints about one directional fixed seats, the HSR-350x's seats are rotatable. HSR-350x will be available to the public in 2007 (proposed).
[edit] Expectations
HSR-350x developement project period is well planned to cover five years, with budget of US42.9 million dollars in total. They expect to develope the Gyeongbu Line's HSR technology, and the increase for the export, and decrease for the import.[1]
[edit] Speed
During the first test, this train did not reach 100km/h. After years of work and testing, however, at 1:20 a.m. on December 16, 2004, the G7 cut through the early morning fog between the Chonan and Shintanjin corridor, just exceeding 350km/h (217mph). The prototype, built by KRRI (Korean Railroad Research Institute), passed the mark of 350 km/h, reaching up to 352.4km/h (218.9mph) which was viewed on the screen, breaking the past record of 343.5km (213mph) on its trial run.

[edit] National and international connections
Korea is the fourth nation in the world to develop high-speed trains independently (after France, Germany, and Japan).[3]In 2006, Korea is the one of seven leading nations in HSR technology (France, Germany, Japan, Italy, South Korea, Spain, and possibly USA).[4] After winning successfully at the bid, six of 10-unit set G-7 trains will be introduced and delivered on Honam Line by 2008. The future goal for Korean is to become one of the top four largest HSR producers in the world, by offering Korean HSR product to China, Taiwan, and America.[5]
