Trelleborg suspension components for Korea's new high-speed train
Trelleborg is supplying Metalastik® half-shell bearings™ for the anti-roll bar system which is designed to limit the movement of the train body as it negotiates the track's curves.
The bushes are mounted in pairs at either end of each anti-roll bar and are designed to provide progressive spring stiffness and maximum flexibility under full load conditions.
Rotem's KTX-II is a unique design using all-Korean technology and is based on the earlier Korean Train eXpress KTX-I, which ultimately derived from the TGV. Although designed to run at speeds up to 330 kmh, KTX-II is capable of 350 kmh and is expected to reach a maximum speed of 400 kmh by 2012, making it by far the fastest of all the commercialized high speed trains. The protoype is due to begin its test programme in 2008.
Rotem has already won the contract for trains on the Honam-Jeolla line, which is due to open in 2009 but the KTX-II will also run on a number of other new lines which are being planned by Korea. In addition, Rotem has received expresions of interest from the USA, Turkey and Brazil.
Rotem is part of the Hyundai Motor Group and, in addition to light rail vehicles, its Changwan-based rail division designs and manufactures electric and diesel locomotives, Maglev and high-speed trains, suburban train units, passenger and freight wagons.
