Switch Gap Detection System
A switch gap detection system is disclosed herein that is configured to monitor a switch installed on a railway, detect a switch gap, and notify a train operator or otherwise take action to prevent a derailment, accident, or other dangerous situation. The switch gap detection system may include one or more switch gap sensors installed on or adjacent to a rail at a location proximate to a switch. The one or more switch gap sensors may be configured to determine a status of the switching points on the switch (e.g., open, closed, or switch gap detected). If the one or more switch gap sensors detect a switch gap, a notification may be provided to a train operator, for example, in the form of an audible and/or visual alert. In some embodiments, a signal may also be sent to automatically stop the train to prevent a derailment.

The first communication unit is configured to receive the locomotive control command from the off-board remote controller interface.
METHOD AND SYSTEM FOR CORRECTING PRECISION OF MAGNETIC LEVITATION TRAIN TRACTION SYSTEM POSITION CONTROL RING
Disclosed are a method and system for correcting the precision of a magnetic levitation train traction system position control ring. The precision correction method comprises: step A, a speed measuring system collecting position-related information of a train; step B, sending the position-related information to a traction system through a signal system; and step C, the traction system carrying out closed-loop control on the position of the train according to the position-related information. The method further comprises step A1 before step A: checking the time for the speed measuring system, the signal system and the traction system, and adding timestamp information. According to the correcting method and system, the time is checked for a speed measuring system, a signal system and a traction system, and timestamp information is added, such that the influences of a delay and periodic random shaking are overcome, and the requirement of traction control of a medium-high speed magnetic levitation train is met. By using mature and cheap 4G-LTE wireless communication, the characteristics of high bandwidth, low delay, wide coverage, QoS guarantee and high-speed movement are achieved. A simple and practical method for improving precision of medium-high speed magnetic levitation magnetic pole phase angles is provided, and this has good engineering application prospects.
Method of operating a rail-guided permanent way machine, and a permanent way machine
A rail-guided permanent way machine is operated by means of a control device in such a way that at least one state variable (Z) of the permanent way machine is determined in dependence on an operating state, and the at least one state variable is compared to at least one pre-defined limit value (G.sub.W, G.sub.S) for monitoring a derailment safety of the permanent way machine. Thus, the derailment safety of the permanent way machine is determined in accordance with the current operating state and monitored. As a result, the permanent way machine has an expanded operating range and increased performance and thus increased efficiency.
End of vehicle device with integrated antenna
A device adapted for attachment to a coupler of a trailing railcar of a train includes an enclosure defining an internal compartment, a port adapted for connection to an air brake hose receiving air from a brake pipe of the train, a handle extending from the enclosure, a communication device disposed within the internal compartment of the enclosure, and at least one antenna connected to the communication device and extending at least partially through the internal compartment of the enclosure and into an internal cavity of the handle.
Distributed bogie diagnostics for track monitoring
A method of monitoring a track using train cars includes collecting first sensor data corresponding to a track location by a first sensor network on a first train car. Based on the first sensor data, a potential track anomaly at the track location is identified by a diagnostics system on the first train car. A message describing the anomaly is transmitted to diagnostics systems located on other train cars. The message is received by a second diagnostics system on a second train car located behind the first train car. The second diagnostics system determines a time at which the second train car will be passing over track location and, at the determined time, collects second sensor data. If the track anomaly is present in both the first sensor data and the second sensor data at the track location, a train control system is notified of the track anomaly.
VEHICLE AND ROUTE MONITORING SYSTEM
A system is provided that may include a first communication controller that may communicate with a vehicle system formed from two or more vehicles. The first communication controller may operate in different modes, including a first mode to control movement of the vehicle system without repeating any control signals communicated between the vehicles, and in a second mode to monitor different frequencies for receipt of the control signals, receive and repeat a first control signal of the control signals at a first frequency, and receive and repeats a second control signal of the control signals at a second frequency. The first communication controller may also operate in a third mode in which the first communication controller may monitor the first frequency but not the second frequency for the first control signal, receives the first control signal at the first frequency, and repeats the first control signal at the first frequency.
