A signal detection system for use with a signaling system is disclosed, the signal detection system comprising a plurality of electrical terminals including a source terminal and an output terminal, the output terminal being connected to a signaling device. An auxiliary terminal electrically coupled to at least one of the plurality of electrical terminals is provided. A current sensor is coupled to the auxiliary terminal for detecting an electrical signal for controlling the signaling device. The current sensor generating an output signal in response to the detection of the electrical signal for controlling the signaling device for monitoring the status of the signaling device. Also disclosed is a method for installing a signal detection system in a wayside signaling system including a signaling device for monitoring a status of the signaling device. An apparatus for connecting a current sensor to a signaling device is also disclosed.

Signal detection system and method

A first unit configured to generate and transmit a code of positive and negative DC pulses through a first rail of a railway. A second unit spaced from the first unit and configured to sense the code, which includes a leading code word, having a positive or negative timing pulse followed after a first data interval by a positive or negative data pulse, followed by a modifying code word. The modifying code word consists of a second positive or negative timing pulse followed after a second data interval by a second positive or negative data pulse. The second timing pulse starts after one code cycle from the start of the leading code word timing pulse. The second timing pulse and the second data pulse duplicate the timing pulse and the data pulse of the same polarity, but invert the timing pulse and the data pulse of opposite polarities.

Railway code generation and signaling system and method

A system includes a determination module and a communication module. The determination module is configured to be located onboard a first vehicle that travels along a first route including a crossing corresponding to an intersection of the first route with a second route. The determination module is configured to be communicatively coupled with a remote crossing module that is configured to impede travel of a second vehicle through the crossing, and to identify an upcoming stop at a station within a range of a track detection system associated with the remote crossing module. The communication module is configured to communicatively couple the determination module to the remote crossing module, and to transmit an inhibit request message to the remote crossing module. The inhibit request message is configured to prevent the remote crossing module from activating a warning when the first vehicle is stopped at the station.

Systems and methods for management of crossings near stations

A transformer core apparatus includes a body of highly magnetically permeable material, a permanent magnet arranged in a safe state position for saturating the body with a permanent magnetic field, and means for removing the permanent magnetic field from the body.

Apparatus and method for safe state retention

Various methods and systems are provided for a crossing equipment controller. In one embodiment, a method comprises prior to a vehicle entering a diverging zone, calculating a travel time until the vehicle at a determined position would reach a crossing based on one or more vehicle conditions, and in response to the vehicle entering the diverging zone, updating the travel time with a time-based countdown.
