Track path e.g. fixed track path, for rail-bound vehicle, has passage part formed by lower side of rail, upper side of track supporting body and rail supports, where passage part enables obtaining uniform wind stream by aerodynamic geometry

摘要

The track path (1) has a platform formed by rails (10) and rail supports, and ballasted track superstructures (2b) rested on a substructure (3). A track supporting body supports the platform, and a passage part is formed by a lower side of the rail, an upper side of the track supporting body and the adjacent rail supports. The passage part enables obtaining uniform wind stream by aerodynamic geometry. The passage part exhibits height ranging between 150 to 200 mm. A supporting point sleeper hump is arranged between rails and rail supports. The supporting point sleeper hump partially consists of resilient material.
