Railway points, railway points operating apparatus and railway track crossing
A railway points arrangement (10) for a railway track junction comprises at least first and second pairs of longitudinally-extending, parallel-spaced static stock rails (12), (14), defining respectively a first route and a second route, and a pair of longitudinally- extending, parallel-spaced switch rails (16) which are movable between a first position in alignment with the first pair of stock rails (12) to select the first route and a second position in alignment with the second pair of stock rails (14) to select the second route. At least one of the movable switch rails (16a) cooperates with at least one stock rail (12), (14) of each of the first and second pairs of stock rails (12), (14) when the movable switch rails (16) are in the first and second positions, and the at least one switch rail (16) and the at least one stock rail (12), (14) are shaped to define a mating profile (50) which aligns the switch rail (16) and stock rail (12), (14) and prevents transverse movement of the switch rail (16) relative to the stock rail (12), (14).
