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 railroad equipment state determination apparatus includes: a storage that stores a plurality of operation data associated with a prescribed operation performed by railroad equipment that is driven by a motor from a stopped state to perform the prescribed operation and then comes into the stopped state again; an evaluation criteria setting section that sets evaluation criteria based on the plurality of operation data stored in the storage; and a determination section that determines whether new operation data resulting from the prescribed operation newly performed by the railroad equipment is abnormal based on the evaluation criteria.

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.

An anomaly determination device includes a changeover force measurement unit that measures a changeover force output by a driving device, the driving device outputting a changeover force for switching a direction of a branch rail whose direction is variable, a voltage measurement unit that measures a voltage supplied to the driving device, a current measurement unit that measures a current flowing through the driving device, and an anomaly determination unit that determines whether or not there is an anomaly in the branch rail, there is an anomaly in the driving device, and there is an anomaly in power supplied to the driving device on the basis of the magnitude of the changeover force, the magnitude of the voltage, and the magnitude of the current.

A switching machine comprises a frame, a point detector bar, an indication contact assembly, at least one detector bar follower able to act on the indication contact assembly depending on the position of the point detector bar relatively to the frame, an inhibiting element jointly movable with the detector bar follower, and a cam bar translatable relatively to the frame between an unlock position and a lock position. The cam bar comprises a tongue portion which is able to be in contact with a stop of the inhibiting element when the cam bar is in its unlock position and to be away from the stop when the cam bar is in its lock position. The inhibiting element comprises a main body relatively to which the stop is vertically translatable between an active position and a passive position.
