RAILWAY TRACK SWITCH Russian patent published in 1998 - IPC

FIELD: railway construction components. SUBSTANCE: this relates to industrial railway transportation and particularly to design of track switches of factory railroads. Switch has pair of rails which are movable in horizontal plane. One of rails which functions as guiding for branching is made curvilinear. Rails of aforesaid pair are rigidly connected to each other by bolts which are inserted through shells located between them. Curvilinear rail is made with rectilinear section. Distance in this section between side edges of rail heads is larger than difference between width of base and width of head of these rails. Shells are installed in aforesaid section with possible resting on bases of rails. This embodiment of switch is aimed at enhancing reliability in operation of switch due to reduced stresses in its main load-bearing components. EFFECT: higher efficiency. 3 dwg
