Estimation on the ride comport and running stability for tilting train on the Gyeongbu line in the Korean rail network (ICCAS 2012)

The development of tilting trains in Korea started in 2001 as research & development project. A 6-car prototype test tilting train, called the Tilting Train eX-press (TTX), was built in December 2006 and experimental trials began in 2007. TTX has distributed power, is designed to run at 200 km/h, and has a planned service speed of 180 km/h. Running time for tilting train is one of the most important factors, with which will be done whether the commercialization of tilting train is needed or not. In this paper, the running time and time saving of tilting train was evaluated compared with today´s conventional trains and non-tilting trains, based on the Gyeongbu line(Seoul ~ Busan 441.7km). We evaluated the potential of a speed-up of tilting trains on curves, on the basis of tilting train trial run data on the Gyeongbu line and present tilting trains´ competitiveness in terms of travel time and speed.
