Definitions

  • the present invention relates to a system and method for co-ordinating and assisting in the performance of railway maintenance operations and/ or the control of railway traffic through areas where signals have failed.
  • the invention relates to a remotely accessible railway operation and maintenance management system.
  • network maintenance is used to indicate maintenance of inter alia railway track, signalling and infra-structure associated therewith, for example a bridge crossing a railway track.
  • PICOP Person in Charge of Possession
  • a typical scenario would be that a load of new track is to be delivered to the "section in possession" (SIP).
  • SIP section in possession
  • the load would arrive by train at the site, where the train would stop, as STOP signs would have been placed prior to the entrance to the SIP.
  • the train driver would telephone the PICOP and inform him of his arrival.
  • the PICOP would telephone the site foreman and ask him to confirm that the SIP was in a safe condition for the train to enter. If the foreman confirmed this, the PICOP would telephone the train driver and tell him to proceed into the site to a designated stopping place.
  • the train driver When the train was at the designated stopping place the train driver would contact the PICOP and tell him of his position. When the new track is to be unloaded from the train a similar set of procedures would be followed. Each time an action on the schedule has been executed the PICOP updates the schedule to indicate that the action has been carried out. Hence, a single person is in control of operations at the site, and a written record indicating when tasks have been carried out is built up.
  • Such a system for organising and managing railway maintenance operations has a number of disadvantages.
  • the use of written schedules as the reference for the maintenance plan does not assist the PICOP in building up a visual image of the scene at the SIP.
  • the tool comprises a magnetic board to which magnetic pieces representing anything that may be used in the SIP, such as track, trains, signs, plant, etc may be attached.
  • This tool is used in the planning meetings. Its use allows problems with the proposed schedule to be appreciated more easily because it presents a visualisation of the track, whereas a written list does not. However, with this tool it is still necessary to have some written information. For example, if a crane is required at a certain point on the track a piece representing a crane may be placed on the track at the given point. However, the requirements of the crane will be stored in a written document, which could be referred to in the planning meeting or by the PICOP when the maintenance is taking place.
  • the PICOP updates the magnetic board. So, if carrying out the same movement of track into the SIP as described above, when the train arrives at the site, the PICOP would place a symbol of a train at the SIP entrance on the track. When the train moves into the SIP the PICOP would move the symbol of the train to the position on the track to which it has moved. The PICOP is therefore presented with an up to date graphic representation of SIP.
  • the magnetic board system provides many advantages.
  • the visual presentation of the SIP to the PICOP represents a significant step forward in safety.
  • JP2008-217221 describes a maintenance work management system where information presentation screens are created for each work site in accordance with the maintenance work plan for each work site.
  • the information presentation screens can be viewed on a management computer and on mobile terminals.
  • the railway maintenance management system described in JP 2008-2 7221 is part of a larger and more complex train operation management system. Whilst the device described in JP2008-217221 does provide for a remote worker to view a maintenance work plan situated on a management computer, the work plan, management computer and remote device do not form part of an interactive system.
  • the current method involves deploying a person at each end of the section of track where the signalling has failed.
  • the person at the beginning of the section of track issues a ticket to the driver of a train before that train may enter the section of track.
  • the person at the other end of the track collects the ticket from the driver when the train leaves the section of track. This system is very consuming of manpower.
  • a computerised railway management system comprising: an operator's computer; a display connected to the operator's computer; software running on the operator's computer, the software configured to: present on the display symbols representing a railway infrastructure including: track, rolling stock, worksites and personnel; and permit a user to: add or remove symbols, and change the position of symbols.
  • the software permits the status of symbols to be changed.
  • the system includes one or more remote computer devices in communication with the operator's computer, wherein the software running on the computer and/ or software running on the remote computer device permit the information displayed on the display to be displayed on a display of the remote computer device.
  • an authorisation code must be entered into the remote computer device to allow the information to be displayed on the display of the remote computer device.
  • the software provides for information to be associated with a symbol and is configured whereby selecting the symbol allows the information to be accessed.
  • the information may include inter alia the number of the train, the direction of travel, the driver's mobile telephone number.
  • the software provides for a table to be associated with the symbol, and preferably the software allows information to be added manually to the table.
  • the software may be configured to populate the table with certain information relevant to the symbol.
  • the software provides a record function, which records images of the positions occupied by symbols at regular intervals, and preferably every occasion a symbol is moved. More preferably, every time a symbol is moved the software causes that action to be time stamped.
  • Another aspect of the invention provides a method of performing railway track maintenance comprising utilising a computerised railway management system comprising: an operator's computer; a display connected to the operator's computer; software running on the operator's computer, the software configured to: present on the display symbols representing a railway infrastructure including: track, rolling stock, worksites and personnel; and permit a user to: add or remove symbols, and change the position of symbols; the method including the steps of: creating a representation of a section of railway and works-schedule for that section of railway on the display and displaying that to an operator; the operator giving an instruction to a person in or immediately outside the section of railway and changing a position or status of, or adding or removing a symbol from the representation.
  • the method may include providing another party with a remote computer device in
  • Another aspect of the invention relates to a computerised system for controlling the passage of railway traffic through a section of track, the system comprising: an operator's computer; a display connected to the operator's computer; software running on the operator's computer, the software configured to: present on the display symbols representing railway infrastructure including: railway track and rolling stock; and permit a user to: add or remove symbols, and change the position of symbols and communication means to permit two way communication between a person operating the software and a driver of a train situated in a controlled section of track.
  • the system includes one or more remote computer devices in communication with the operator's computer, wherein the software running on the computer and/ or software running on the remote computer device permit the information displayed on the display to be displayed on a display of the remote computer device.
  • the two-way communication means may be comprised in the remote computer device.
  • the two-way communication means may be a telephone or radio for example.
  • Another aspect of the invention relates to a method of controlling the passage of railway traffic through a section of track, utilising a system comprising: an operator's computer; a display connected to the operator's computer; software running on the operator's computer, the software configured to: present on the display symbols representing railway infrastructure including: railway track and rolling stock; and permit a user to: add or remove symbols, and change the position of symbols and communication means to permit two way communication between a person operating the software and a driver of a train situated in a controlled section of track; the method comprising the steps of: communicating with the driver of a train situated in immediately outside a controlled section of track; and updating the position of a symbol representing the train to correspond to the actual position of the train confirmed by the driver of the train.
  • the method may comprise the step of providing to the driver of the train a remote computer device configured to communication with the operator's computer, wherein the software running on the computer and/ or software running on the remote computer device permit the information displayed on the display to be displayed on a display of the remote computer device to the driver of the train.
  • an operations room for controlling maintenance operations on a railway including: an operator's computer; a display connected to the operator's computer; software running on the operator's computer, the software configured to: present on the display symbols representing a railway infrastructure including: track, rolling stock, worksites and personnel; and permit a user to: add or remove symbols, and change the position of symbols.
  • the operations room includes at least two displays connected to the operator's computer, at least one of the at least two displays being a different size to another of the at least two displays.
  • one screen would be relatively large (for example 60 inches) and another would be the same size as a typical computer monitor or the same size as the screen of a remote computer device, such as an I-pad. This provides for the operator of the operator's computer to satisfy himself that a worker looking at the display on a remote computer device can see what the operator sees on the large screen.
  • the system for controlling the passage of railway traffic through a section of track is particularly useful where the signalling through a section of track has been disabled. This happens regularly due to breakdowns and the theft of signalling cables.
  • the signalman (or a person carrying out the function of the signalman) would operate the software on the computer whilst viewing the display.
  • the train driver comes to the stop signal preceding the area where signalling has failed he would communicate his position to the signalman.
  • the signal man would look at the display and introduce a symbol of a train at the location of the stop sign on the displayed representation of the railway track.
  • the signalman would assess whether it was safe for the train to proceed into the section of track and then give a command to the driver of the train to enter the track, and another command of where to proceed to.
  • the command may be to enter the section of track and proceed to a station within the section, or to proceed through the end of the section, stop and wait for further instructions.
  • the system would be operated according to a protocol whereby each time the signal man gives an instruction the train driver confirms to the signalman that he has received the instruction and will execute the instruction. The train driver then confirms to the signalman that he has carried out the instruction. The signalman constantly updates the status of the train and its position in or with respect to the area of track where the signalling has failed.
  • the signalman moves the symbol of the train to the destination.
  • the train driver has a remote computer device in communication with the signalman's computer. This allows the train driver to view the same information as viewed by the signalman.
  • the signalman operating the system gives instructions to the train drivers.
  • the signalman may also or alternatively give instructions to personnel located at the railway trackside, who then give signals to the train drivers using signalling systems common to the industry.
  • the present invention provides a number of advantages which will enhance railway maintenance safety and reduce the time spent in and travelling to planning meetings.
  • the ability to have information relevant to a particular work site or piece of plant entering the worksite associated therewith is a significant step forward.
  • the PICOP would have had to refer to a written log in paper form.
  • SIP's may be one hundred and thirty kilometres long, only a small part of the SIP will be visible to the worker. For some information he will be completely reliant on the PICOP.
  • the invention allows the worker to see the current status of the area SIP via a remote computer device, which could be a smart telephone for example.
  • the worker may also be able to view the information associated with the symbols, if the worker concerned has been given the appropriate authorisations.
  • the PICOP can be inundated with requests for information at a time when he needs to be focussing on the maintenance work in hand.
  • interested parties could be given access to the system so that they could see for themselves the status of the maintenance, without having to contact and hence disturb the PICOP.
  • the provision of access to the information presented to and controlled by the PICOP to a number of other people in the SIP, most of whom will be knowledgeable people in the field of railway maintenance, will act as a natural safety check to pick up mistakes made by the PICOP. For example, if the PICOP has instructed a driver to bring a train to a certain point in the area under possession, but then forgets to update the system, this is likely to be noticed by workers in the SIP. In the system that is currently used, the workers on the SIP cannot see what the PICOP sees. Hence, accidents due to human error are likely to be reduced.
  • the most commonly used system for performing maintenance operations involves only paper documentation.
  • the PICOP will often operate from a vehicle. Most railway maintenance work is conducted at night, so the PICOP must rely on the vehicle's internal lighting to view the information he has and update that information. This limits the size of possessions any one PICOP can deal with to about ten miles.
  • the system of the invention also provides a means of recording events, including the PICOP's voice. This will be particularly useful in the event of an incident, and also in training of personnel.
  • Figure 1 is a representation of the information displayed graphically by the system of the invention.
  • Figure 2 is a block diagram of an operations room according to an aspect of the invention
  • Figure 3 is a block diagram of an operations room according to another aspect of the invention
  • Figure 4 is an illustration of symbols linked to aerial images
  • Figure 5 illustrates the different information presented to the user of the system.
  • Figure 6 represents the interface with a database of the system.
  • FIG. 1 there is shown a computer screen 1 having represented thereon four sections of track 2 to 5.
  • the four sections of track represent a single stretch of track in possession, the ends thereof being denoted by arrows 6a, 6b and an indication of the next stations 7a, 7b.
  • the track is divided so that it fits onto the computer screen 1.
  • the divisions in the track are marked by letters: A, B, C.
  • symbols representing fixed infrastructure associated with the sections of the track 2 to 5, such as bridges 8, underpasses 9, tunnels 10, stations 11 and signals 12 are shown on the computer screen 1 at a location on the track that is representative of the position of the item of infrastructure on the actual track that is represented.
  • the representation of the sections of track and infrastructure on the computer screen are not necessarily scaled representations of the actual track.
  • symbols representing four worksites 3 to 6, and the infrastructure associated with planned maintenance at these worksites are shown on the track representation. For example, an excavator 7 is present in the first worksite 3.
  • the symbols When used as a planning tool, all the symbols may be moved around. Further, the software provides a library of different symbols depicting all items that it may be desired to represent. When the maintenance plan has been agreed some of the symbols will require a level of authorisation above the PICOP to change. The PICOP is free to move the symbols representing items that may be moved into and out of, or within, the section of track in possession.
  • FIG. 1 Also shown in Figure 1 is an information table 19 associated with a train 18 that is shown situated at a station 20. When the train 18 is selected the user is given the option to view the table 19.
  • the table sets out some pre-determined information and provides for the recording of future events.

  • the PICOP needs to know when and where they are working within the "possession", but does not give instructions to those staff.
  • the PICOP updates all information via the database user interface. Hence, the information contained in the symbol data window 32 of Figure 5 is updated by entering information into the system database.
  • the software includes a database interface which provides for information on the screen to be updated. Some of the information is updated automatically. For example, the information contained in the symbol data window is updated automatically. Other information is not updated automatically. For example, when a train is going to enter the possession, the PICOP goes to the "train entering possession" tab 43 and enters information relating to the train about to enter the possession. This information is sent to the database link 35. From this link the PICOP drags and drops symbols to update the track image.
  • the symbols used in the system may have rules associated with them that create reminders to the PICOP.
  • the stop sign at the beginning of a possession may have a rule associated therewith that highlights to the PICOP that only a signalman can authorise a train to pass the signal.
  • the software may be configured so that the rule is brought to the attention of the PICOP when the cursor is passed over the symbol representing the signal.
  • Another rule may cause some parts of the track to change colour, if for example a train is scheduled to cross from one track to another.
