Abstract
In a railway switch there are used actuator means (8, 12, 14; 9, 13, 15) co-acting with drive means (16; 17) to move the points (4; 5) alternatively in a vertical direction between an active position in which the tread surface (4b; 5b) of respective points lie on the same level as the tread (2b; 3b) on the head of an adjacent rail, and a lowered inactive position out of the path of a flange (6a; 7a) of a flanged wheel (6; 7) running on the tread of the stock rail (2; 3). The means for actuating the points (4; 5) includes arms (8; 9) which, while using the intrinsic resilience of the points, can be swung about horizontal axes (10; 11) located on the sleepers (1) centrally thereon. The points (4; 5) and the stock rails (2, 3) have provided thereon mutually co-acting and mutually engaging guide surfaces (2e; 4e; 3e; 5e) which guide the points in their pivotal movement between their active and inactive positions. A spacer block (18; 19) inserted between respective stock rails (2; 3) and points (4; 5), the width of which spacer block increases from the tip of the point to the root thereof. The spacer block has provided thereon a guide surface (18e; 19e) for co-action with a corresponding surface (4e; 5e) on the point (4; 5). Protection is also sought for a method of switching the points in a railway switch of this kind.
