A mechanism for use in a railway switch machine includes an elongate contact body having a housing formed from a non-conductive material, a plurality of electrical contact rails disposed in or on the contact body, and a contact block slidably coupled to the contact body such that the contact block can generally freely slide along the contact body. The contact block has a plurality of moveable contacts positioned thereon facing the contact body and is structured to engage a point detector bar of the railway switch machine. The contact block is moveable along the contact body from among: a first position in which a first and second rail of the plurality of contact rails are electrically connected and a third and fourth rail of the plurality of contact rails are electrically connected, and a second position in which only the second and third rails are electrically connected.

Disclosed is a railroad switch device for moving railroad switch points. The device includes two spring assembly sets placed over two switch operation rods. The spring assembly sets move railroad switch points and keep railroad switch points against a stock rail. At least one sensor is mounted adjacent to two switch operation rods. The switch operation rods have a switch point position target connected to the switch operation rods. The switch point position target follows a movement of two throw rods. The two spring assembly sets provide a spring holding force to the two switch operation rods. The spring holding force provides a safe operation of a switch point position assembly by at least one of determining that the spring holding force is present in the moving railroad switch point, and pushing the spring holding force towards the switch point position assembly away from the at least one sensor.

Disclosed is switch lock device of a railway switching actuator connected to a switching slide and a tie bar/locking slide of the actuator, the switching slide and a tie bar/locking slide being slidable one over the other to lock a blade of a railway switch in a closed position, the switch lock including an oscillating catch unit oscillating between two positions, engaging either a stationary step of a casing of the actuator or a head surface of the switching slide. The oscillating catch unit links to the end of the tie bar by a spring actuated mechanism blocking oscillation of the oscillating catch unit in an unlocked position corresponding to the engagement of the switching slide. During switching, the tie bar compresses the spring actuated mechanism, and the oscillating catch unit is free to oscillate towards a locking position, engaging the step of the casing of the actuator.

A vehicle management system communicates with monitor devices coupled with a path control device at an intersection between route segments. The path control device switches positions to connect different combinations of the route segments. The system receives signals from the monitor devices to determine which of the route segments are coupled with each other and receives an authority signal from a travel authority system that indicates which of the route segments that the vehicle is authorized to travel. The system directs the vehicle through the path control device responsive to a combination of: (a) receipt of the authority signal and (b) receipt of at least one of the monitor signals or failure to receive one or more of the monitor signals.

A locking device on two bodies movable in a sliding manner relative to each other on a sliding track has a locking pin (7) which is guided in a straight-line mechanism in the guide body transversely with respect to the sliding track and is movable in the expelling direction. A socket spanner is guided in a sliding manner parallel to the sliding direction in the guide body. The locking pin (7) projects with an actuating end into a pocket of the socket spanner. The pocket has edges and surfaces for expelling and inserting the locking bolt and for blocking the straight-line mechanism. The locking device is suitable in particular for the connection and aligning movement of two guide bodies as occur in particular in a point operating mechanism.

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.
