Railway Points, Railway Points Operating Apparatus and Railway Track Crossing

摘要

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.

1. A railway points arrangement for a railway track junction, the railway points arrangement comprising:
at least first and second pairs of longitudinally-extending, parallel-spaced static stock rails defining respectively a first route and a second route; a pair of longitudinally-extending, parallel-spaced switch rails movable vertically and transversely between a first transverse position in alignment with the first pair of stock rails to select the first route and a second transverse position in alignment with the second pair of stock rails to select the second route; wherein at least one of the movable switch rails cooperates with at least one stock rail of the first pair of stock rails when the movable switch rails are in the first transverse position and with at least one stock rail of the second pair of stock rails when the movable switch rails are in the second transverse positions, said at least one switch rail and said at least one stock rail being shaped to define a mating profile which aligns the switch rail and stock rail and prevents transverse movement of the switch rail relative to the stock rail when the switch rails are in the first transverse position or the second transverse position, the mating profile being formed by an upper surface of the stock rail and a lower surface of the switch rail.
