A switching apparatus comprising a point detector connecting rod connected at one end to a switch machine and to at least one point at the opposite end. The point detector connecting rod is attached to the point via an angled block that permits a sliding motion relative to the point.

A turnout includes a fixed beam, and a first and a second movable beams respectively on two opposite sides of the fixed beam. The fixed beam is arranged on a turnout platform. The first movable beam is movably arranged on the turnout platform between a first and a second positions. The second movable beam is movably arranged on the turnout platform between a third and a fourth positions. When the first movable beam is at the first position, the second movable beam is at the third position, the first movable beam is separated from the fixed beam, and the second movable beam and the fixed beam form a first passage; when the first movable beam is at the second position, the second movable beam is at the fourth position, the second movable beam is separated from the fixed beam, and the first movable beam and the fixed beam form a second passage.

A switch device for moving switch rails. The switch device includes a motor operatively coupled to move the switch rails into and between first and second positions. The motor is configured for electricity to flow therethrough along a first path and a second path. A first path relay has two normally open contacts each within the first path, where activating the first path relay closes the two normally open contacts thereof. A second path relay has two normally open contacts each within the second path, where activating the second path relay closes the two normally open contacts thereof. The motor moves the switch rails towards the first position when the first path relay is activated and the second path relay is deactivated, and the motor moves the switch rails towards the second position when the second path relay is activated and the first path relay is deactivated.

A track switch that comprises track rails of basic (2), (3), straight, (4), (5) and lateral (6), (7) directions fastened on a slab track (1); sliding switch rails (8), (9) and point rails (10), (11) that are rigidly fastened to the slab track (1) by means of mounting means (12). The point rails and switch rails form points. The track switch comprises also a shift mechanism with a drive (14) and an axis (15), whereto sliding locks (16), (17) are connected. The point rails (10), (11) and the switch rails (8), (9) are connected with each other by means of units. Each of the units is a guide (18) that is rigidly fastened to the point rail, a wedge (19) that is rigidly fastened to the switch rail (8), (9), a cleat wedge (20) placed in the guides that is capable of moving longitudinally and fastened with its both ends to point rods (21) of the wedge (see FIGS. 1 and 4). The sliding wedges (20) are connected to each other by means of point rods (21), the last of the point rods being connected with the axis of the shift mechanism that is capable of rotating or moving longitudinally, and is set into motion by a shift drive mechanism. The sliding switch rails (8), (9) are connected to each other by means of spacing rods (22).

An improved switch point machine is provided which can seal out water, even if the machine itself becomes submerged. The operating rod and the point indicating rod that extend out of the switch box housing should be ground round and have a smooth surface for an improved seal. Those rods are preferably chrome plated. Dynamic hydraulic seals can be used to seal out moisture. Internal components, within the switch box housing, should also be sealed to be water resistant in the event water does enter the housing.

The present invention provides a measuring assembly (11) for measuring a characteristic of the movement of a first rail relative to a second rail. The measuring assembly comprises a measuring gauge (15) for measuring the characteristic and a rail movement detection device (13) to which the measuring gauge is removably secured. The detection device comprises a first subassembly (19) and a second subassembly (39) wherein the first subassembly and second subassembly are slidably interconnected. The first subassembly comprises a first rail engagement portion spaced from a first end (23) of the first subassembly. The second subassembly comprises a second rail engagement portion spaced from a first end (43) of the second subassembly. The measuring gauge is secured between the first end of the first subassembly and the first end of the second subassembly. Movement of the first rail engagement portion relative to the second rail engagement portion causes the first end of the first subassembly to move away from the first end of the second subassembly, the characteristic of the movement being measured by the measuring gauge.

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.
