Definitions

  • the present invention relates to railway control and protection systems and in particular to the safe movement of trains along a railway line.
  • a railway control system comprises trackside devices such as train detection equipment, point machines to set, lock and determine the lie of routes and lineside signals by which to communicate the authority to proceed to train drivers. These trackside devices are connected to an interlocking which determines the safe logic state of these devices according to controls emanating from a control centre and the positions of trains on the railway.
  • FIG. 1 shows the addition of RBC equipment conventionally to an existing signalling system, where RBC equipment 4, of which there may be a plurality, is shown communicating by radio with a train 5 and directly with the interlocking equipment 2, an additional interface between the RBC 4 and the control centre 3 also being shown.
  • RBC equipment 4 of which there may be a plurality
  • the present invention provides a means of adding automatic train protection to an existing conventional signalling system without requiring any change to the functionality of the existing system.
  • the present invention communicates movement authorities to trains in a manner that is independent from the prior art interlocking to trackside device architecture such that its provision requires no alteration to the interlocking nor impinges upon the connections between the interlocking and trackside devices.
  • the train protection system may therefore be overlaid on existing railway control systems.
  • a train protection and control system suitable for use with an existing signalling system without requiring any functional change to the signalling system, the signalling system comprising a plurality of railway trackside devices, an interlocking connected to the trackside devices for controlling the trackside devices and a control centre connected to the interlocking, wherein the train protection and control system provides diverse means of protection of movement of a train by transmitting movement authorities to the train independently of the interlocking, characterised in that control, indication and state of the railway information are acquired directly from the interface between the control centre and the interlocking by a device which listens to the communication of information on the interface.
  • the present invention also comprises such a train protection and control system overlaid on to said signalling system.
  • the interface between the control centre and the interlocking and the information communicated across it is regarded as non-safety critical.
  • the present invention advantageously utilises this information to provide automatic train protection and increases the overall safety of the railway.
  • the control, indication and state of the railway information may be evaluated to provide information to a radio block centre to enable movement authorities to be transmitted to trains via a radio system.
  • consistency checks are undertaken of the state of the railway to ensure the validity and increase the integrity of the information being passed to the radio block centre and to take action when an invalid situation is detected.
  • the system may provide for independently checking new movement authorities from the radio block centre in relation to other movement authorities already issued before authorising issue of the new movement authority.
  • transmission of the independent movement authority to a train is effected by the established art whereby a radio block centre (RBC) and a train carried on-board computer (OBC) communicate via a radio system.
  • RBC radio block centre
  • OBC train carried on-board computer
  • Movement authorities are derived from the control system interface and sent independently to the train such that the OBC can monitor movement of the train and provide automatic train protection (ATP).
  • ATP automatic train protection
  • a logic processor device 6 is arranged to acquire control, indication and state of the railway information by listening to the information flowing each way between the control centre 3 and interlocking 2. With this information the logic processor device 6 continually evaluates the state of the railway to determine, for example, which routes are set and the positions of trains within the railway. As part of the evaluation, checks are undertaken to ensure consistency and validity of the information before the results of the evaluation are passed to an RBC 4. Failure of these checks to pass, results in an alarm being raised and the railway protection system entering a restrictive state.
  • the RBC 4 From the information received from the logic processor device 6 the RBC 4 generates movement authorities ready for transmission to the on-board computers (OBCs) 5 of trains via the radio system. Before transmission is permitted an independent safety monitor (ISM) 7 checks each new movement authority to ensure it does not conflict with other movement authorities that are already current or being transmitted. If a conflict is detected, the new movement authority is rejected, an alarm raised and the railway protection system entered into a restrictive state.
  • ISM independent safety monitor
  • the invention has been described in terms used by the European Rail Traffic Management System (ERTMS) but is applicable to any radio based train control and protection system.
  • ERTMS European Rail Traffic Management System
  • control centre 3 provides interlocking and control information directly to the logic processor device 6 by reflecting information on the control centre to interlocking interface through a dedicated communication port provided for this purpose.
