Abstract
A railway structure for a sliding chair (2), a sliding plate and a ribbed plate (1), respectively, for railway switches or railway crossings. The structure includes friction-reducing sliding members (4, 5) of synthetic plastic material being releasably mounted within recesses (3) in the sliding chair (2) and the plates, respectively. There are accommodated within each recess (3) at least two sliding members (4, 5) having their side surfaces engaged over the major part of the periphery by inwardly protruding walls or profiles of the edge of the recess, so that there results a safe mounting in position of the sliding members (4, 5). The structure makes the interchange of the sliding members a simple procedure.
