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 supplemental power source connectable to a standard railroad track switch power source. A pair of electrical connectors (A) form a supplemental power source circuit input. Another pair of electrical connectors (B) form a supplemental power source output and are configured for connection to a standard railroad track switch. An electrical conductor connects a first one of the supplemental power source output connectors (B) to a first one of the supplemental power source input connectors (A). A diode is connected between a second one of the supplemental power source input connectors (A) and a second one of the supplemental power source output connectors (B). The diode is connected to prevent current flow to the standard railroad track switch power source. An ultracapacitor is electrically connected between the electrical conductor and the second one of the supplemental power source output connectors (B).

The disclosure relates to a non-national standard turnout drive system based on a double 2-vote-2 architecture, including an interlocking processing subsystem IPS, an interlocking maintenance station SDM, a non-national standard turnout drive module HIOM and an interlocking maintenance station SDM, wherein the non-national standard turnout drive module HIOM, a full-electronic communication module EIOCOM2, and the interlocking processing subsystem IPS are connected with each other in order, and the full-electronic communication module EIOCOM2 is connected to the interlocking maintenance station SDM; two non-national standard turnout drive module HIOMs, which are mutually redundant, obtain turnout drive commands through the interlocking processing subsystem IPS to control drive relays in a non-national standard turnout to lift and fall for driving the turnout to rotate toward a specified direction, while collecting representation information of the turnout and determining a position of the turnout. Compared with the prior art, the disclosure has advantages of high reliability and strong maintainability.

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.

For fault detection in a switch system including multiple switches, for a respective switch its operating data are acquired and transmitted to a central control. For a respective first switch of the switch system, a deviation of an operating behavior of the first switch from a set behavior is determined by the central control on the basis of its operating data. If there is a deviation, operating data of the first switch are compared with operating data of other, second switches of the switch system and, depending on that, a second switch with similar operating data is selected.

The present disclosure provides a system for securing communication between Central Controller and signaling devices including actuator devices and signaling sensors used in railway and road traffic signaling networks. Conventional signaling systems use unsecured metal cables to communicate between the Central Controller and the signaling devices, making them vulnerable to unauthorized intrusion and mischief. In the present disclosure, two uniquely addressable communication modules, one (SCM1) securely housed with the Central Controller and another (SCM2) securely housed in an assembly also containing the signaling device and the related power switches are used to establish a transparent but standard secure digital communication protocol between them to authenticate and validate mutual communication, making them secure and safe from intrusion and undesirable manipulation.
