Slab Track Design for High-speed
If the low-maintenance characteristics of slab track on open line are to be retained, great care must be taken to ensure that the subgrade layers are homogenous and capable of bearing the loads imposed [2]. The slabs can be precast or poured on site. The most known tracks with precast slabs are Shinkansen line in Japan and Max Bögl slab track designed in Germany [2], while as examples of the tr...
متن کاملInterior Noise of a Korean High-Speed Train in Tunnels
High-speed trains with the maximum speed of 300 km/h, named as Korea Train Express (KTX), have started revenue services since April 2004. Because of the geomorphologic conditions of Korea a large portion of the ‘Kyung-Bu’ line is comprised of tunnels or bridges, which may cause excessive noise in a vehicle. The vibration generated by the trains propagates into the tunnel and the vehicle structu...

The purpose of this study is to provide a model with a dynamic system method to investigate the factors affecting the technological capabilities enhancement in the high-tech industries of high-speed train of the rail transportation system. For this purpose, after reviewing the literature and conducting several meetings with experts in the rail transportation industry, a conceptual and qualitati...
متن کاملPantograph noise measurements in Madrid-Sevilla high speed train (AVE)
Ten years ago, the first Spanish high speed line which traveled from Madrid to Sevilla at an average speed of 250 km/h was inaugurated. At this speed pantograph noise, which is of an aerodynamic nature, is thought to have rather influence in the passengers zone. However, pantograph contribution is often omitted since main noise sources are expected to come from wheels and devices placed under t...
متن کاملNew Model of Cement Product – Precast Slab Track for Thsr (taiwan High Speed Rail)
The development of “slab track” was started by Japan in 1955 and the “Committee of slab track research” was established in 1971 for exclusive development of slab track. This makes Japan the country that has invested the most effort into slab tracks. On 5 January 2007, the THSR transferred from Japanese Shinkansen started its commercial operation. The stability and comfort of train operation hav...
