A signal-controlled crew warning system for warning people of approaching rail vehicles on an operational track located in a warning sector of a work track. The warning system includes a track-building machine for working on the work track, a positioning system for determining the position of the track-building machine, a computer-aided monitoring system for generating warning information, warning measures for generating acoustic or optical or haptic warning signals, and a radio system for wireless data transfer. The computer-aided monitoring system is configured to set boundaries of the warning sector on a basis of the current position of the track-building machine and to automatically generate warning information for the warning sector. The track-building machine has a central control unit for processing the warning information, which control unit is coupled to the computer-aided monitoring system via the radio system. The warning sector thus moves along with the track-building machine as it travels.

A system for enhancing personnel safety on a railroad track is presented. The system can receive data from sensors and/or a PTC system to determine positions of clients/worker and/or vehicles, and further utilize such data to determine if a vehicle is within a certain proximity of the client/worker location. The system can further generate geofences around clients/vehicles to and determine when such geofences intersect one another. Additionally, the present disclosure can assign severity levels and generate alerts with the assigned severity levels, and such severity levels can indicate how close a vehicle is to a particular location. It is an object of the invention to provide a system for generating alerts to notify personnel when they much retreat to a place of safety.

Systems and methods are provided for decentralized rail signaling and positive train control. A decentralized train control system may include a plurality of wayside units, configured for placement on or near tracks in a railway network, and one or more train-mounted units, each configured for use in a train operating in a railway network that support use of the decentralized train control system. Each train-mounted unit may configured to receive communicate with any wayside unit and/or train-mounted unit that comes within range, with the communicating including use of ultra-wideband (UWB) signals, and for generating control information based on the UWB signals, for use in controlling one or more functions associated with operation of the train.

An exemplary method includes electronically determining that movement of a rolling stock should be prevented based on a failure condition of the rolling stock. And if it is electronically determined that movement of the rolling stock should be prevented based on the failure condition of the rolling stock, the method further includes preventing movement of the rolling stock including preventing the rolling stock from initiating a movement from a stationary position along a track within a work area defined around the rolling stock by: preventing brakes of the rolling stock from being released via one or more pneumatic components; and/or preventing the rolling stock from receiving or accepting a movement command.

The present disclosure generally relates to a rail warning system using wireless portable transmitters/receivers. The rail warning system uses a chirp spread spectrum modulation scheme, and alerts personnel in work zones on or near train tracks as well as optionally, on track equipment and train operators, of approaching trains or on track equipment. Portable wayside devices may also be positioned on the rail web, optionally magnetically, to alert work personnel, allowing for secure placement but also portability to other locations on the same track or adjacent tracks.
