WebThe FST structures consist of discontinuous floating slabs with a length of 20 m, a width of 2.8 m, and a height of 0.4 m supported by two rows of springs with a stiffness of 6.9 MN/m. Therefore, the natural frequency of the FST is approximately 8 Hz. The detailed properties of the rail, fasteners, and the FST are listed in Table 8.4. Table 8.4. WebNew metro rail construction technology. Because the underground in tunnels is usually stiff and stable, a tunnel is the perfect location for slab track railroad construction. The application of slab track in tunnels is very efficient in terms of railway construction, durability, strength and costs.

WebAug 27, 2024 · Railway Slab Track Construction - Eisenbahn Rheda2000 Betonoberbau Konstruktion 2015 Early slab track projects a range of construction types, sub-bases and fastening technologies. The following list contains construction types of ballastless tracks that have been internationally used in heavy-rail systems (as opposed to light railways, tramways, or metros) in chronological order of their first usage. … See more A ballastless track or slab track is a type of railway track infrastructure in which the traditional elastic combination of ties/sleepers and ballast is replaced by a rigid construction of concrete or asphalt. See more In ballastless tracks, the rails are rigidly fastened to special types of concrete ties/sleepers that are themselves set in concrete. Ballastless tracks therefore offer a high consistency in track geometry, the adjusting of which is not possible after the concreting of the … See more Baulk track and slab track are similar in that the rails are continuously supported, compared to ordinary track where the rails have to "bridge" the gaps between the sleepers.
