Ballastless Track Ensures a High-Quality Ride

Ballastless track is a distinctive feature of the new high-speed rail line serving Taiwan’s west coast. It is served by a fleet of 300 km/h Shinkansen trainsets over a 346-km route. The end-to-end journey time is intended to be as short as 90 minutes on the express train. Semi-fast service with more stops is also planned. Because of tight constraints, the trackwork was especially challenging. Tectonic forces had to be accommodated in track and ballast design, forcing much of it to be built on elevated structures and with completely ballastless track. The choice of ballastless track required close coordination with support structures and other elements in the new line. Design guidelines had to be developed just for this project. Cam plates and slab segments were used, along with new elements, know as floating slabs and rotating slabs. Schematic drawings of the different solutions are supplied, along with photos and descriptions.
