A system that includes a controller that may receive one or more input characteristics related to upcoming movement of a group of vehicles, the one or more input characteristics indicative of an amount of energy needed to move the group of the vehicles along a segment of a route. The controller may also calculate a threshold range of tractive effort needed to move the group of the vehicles along the segment of the route based on the one or more characteristics and to monitor the tractive effort expended by a propulsion-generating vehicle of the vehicles in the group to move one or more of the vehicles in the group, and determine whether the vehicles in the group are coupled with each other or whether two or more of the vehicles are not coupled with each other based on the tractive effort that is monitored and the threshold range.

A disclosure relates to a degradation management method for a versatile signal system, a device and a medium. The versatile signal system supports both the CTCS system for the national railway and the CBTC system for the urban railway; the method controls the safety of trains equipped with the CTCS system or the CBTC system on the same line, and effectively conducts degraded operation management; and the management method comprises switching between normal operation modes of the CTCS system and the CBTC system, switching between degraded operation modes, and switching between normal operation modes and degraded operation modes in a shared area. Compared with the prior art, the disclosure has the advantage that effective degradation operation mode management on trains running on a line under a CTCS+CBTC signal system is realized.

A method and system for managing guided vehicle traffic over a railway network include a first ATS system regulating guided vehicle traffic over a first regulation domain and a second ATS system regulating guided vehicle traffic over a second regulation domain. The first and second regulation domains have a common boundary. The first ATS system sends, to the second ATS system, configuration and circulation data for a part of the first regulation domain, for regulating guided vehicle traffic on the part according to a set of regulation data from the second ATS system. The second ATS system determines, from received configuration and circulation data, regulation data for an extended regulation domain including the second regulation domain and the part and for sending to the first ATS system the set of regulation data regulating the guided vehicle traffic on the part of the regulation domain of the first ATS system.

Systems and methods are provided for decentralized train control. A decentralized train system may include a plurality of wayside control units, configured for placement on or near tracks in a railway network, and one or more train-mounted units, each of which being configured for use in a particular train. Each wayside control unit may obtain information corresponding to each train that passes within its communication range, and provide obtained train-related information to each train-mounted unit passing within its communication range. Each train-mounted unit may configured to receive train-related information from each wayside control unit that comes within its communication range, process the received train-related information, assess based on the processing of the train-related information conditions relating to operation of train within the railway network, and when at least one condition meets one or more particular criteria, perform or cause performing one or more responsive actions.

A monitoring system is provided that may include a sensor configured to detect at least one characteristic related to at least one axle of a first vehicle. The monitoring system may also include a controller having one or more processors in communication with the sensor. The one or more processors may be configured to restrict movement of the first vehicle based at least in part on the at least one characteristic related to the at least one vehicle axle, and vary movement of a second vehicle based at least in part on the at least one characteristic related to the at least one vehicle axle.

A method operates a safety-critical system, which system contains at least one first data device having approved, safety-relevant software and at least one reference data device having the same approved, safety-relevant software. In the method, after a type check of the system, the at least one first data device is equipped with at least one piece of non-safety-relevant additional software and the at least one reference data device is blocked from software modifications. Before safety-related data information is output, output information of the at least one first data device and of the at least one reference data device are checked for a match with regard to the safety-relevant software by a comparison device, and the safety-related data information is output in the case of a match.
