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).

A test release mechanism for a railway switch machine includes a block structured to attach to a lock box in order to move in conjunction with the lock box and a lift pin structured to be operable to selectively engage and disengage the block with a slide bar.

The present disclosure discloses an interlocking protection device for turnout switching. The interlocking protection device for turnout switching comprises a receiving module, a confirmation module, a processing module, and a centralized control interlocking module, wherein the receiving module is configured to receive a turnout switching instruction; the confirmation module is configured to receive a confirmation instruction; the processing module is configured to determine a target turnout position according to the turnout switching instruction and output a driving confirmation signal according to the confirmation instruction; and the centralized control interlocking module comprises a confirmation unit and a position switch unit. Under a centralized control mode, the confirmation unit carries out separate turnout locking according to the target turnout position and carries out locking confirmation according to the driving confirmation signal. After locking confirmation, the position switch unit closes target turnout position switches and opens the other turnout position switches.

Method for detecting rail switches degradation and failures, the method having the steps of applying a Discrete Wavelet Transform to stored measurement data relative to a switch move to be analysed and obtaining a feature vector associated with said switch move and including Discrete Wavelet Transform coefficients delivered by the applied Discrete Wavelet Transform; comparing the obtained feature vector with feature vectors associated with rail switch moves previously obtained and associating each to a respective health class among several given health classes; and determining a health class for the said switch move to be analyzed by selecting one of the health classes associated with the previously obtained feature vectors based upon the comparison step.

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.

Disclosed are a railroad switch device for moving railroad switch points. The railroad switch device comprises a switch housing having a first switch operation unit coupled to a first spring unit and a second switch operation unit coupled to a second spring unit to move the first switch operation unit and the second switch operation unit independently; two sensing units, each connected with each of the first switch operation unit and the second switch operation unit to detect a connection status of the first switch operation unit and the second switch operation unit; and a hydraulic manifold to control the movement of the first switch operation unit and the second switch operation unit.

A switch locking system and method of an authorized locomotive for safely traversing a switch in a railway including sending a lock command from a computer onboard the authorized locomotive to a switch controller associated with the switch; determining if a lock confirmation from the switch controller is received by the computer onboard the authorized locomotive; and safely traversing the switch upon receipt of the lock confirmation. The switch locking system and method may include sending an unlock command from a computer onboard the authorized locomotive to a switch controller after the train clears the switch.

A railroad switch circuit controller assembly includes a switch frame configured to be mounted to a stock rail, and a switch controller held by the switch frame. The switch controller includes at least one switching mechanism. The switch controller includes a point detection rod operatively connected to the at least one switching mechanism. The point detection rod extends a length from a proximate end portion to a distal end portion. The proximate end portion of the point detection rod is located closer to the stock rail as compared to the distal end portion when the switch frame is mounted to the stock rail. The railroad switch circuit controller assembly also includes a switch foot configured to be mounted to a switch rail, and an external rod operatively connected between the switch foot and the point detection rod of the switch controller such that the external rod is configured to translate linear movement of the switch foot toward and away from the stock rail to the point detection rod. The external rod is connected to the proximate end portion of the point detection rod.

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.
