Definitions

  • the invention firstly relates to a method for securing a train travelling along a railway track provided with railway signs.
  • a method for securing a train travelling along a railway track provided with railway signs comprising the steps of establishing a radio contact between the train and a specific railway signal which the train is approaching; transmitting a mode of the railway signal to the train by means of said radio contact; when the mode of the railway signal requires a braking of the train, determining whether such a braking is initiated by the driver of the train; and when, in such a case, no braking is initiated by the train driver, initiating an automated braking of the train.
  • a method which also functions very well at low train velocities, specifically at train velocities under 40 km/h.
  • inventive method basically may be used at the entire practical velocity range of the train, if desired.
  • the step of establishing a radio contact between the train and the railway signal is initiated by a beacon positioned alongside the railway track at a predetermined distance ahead of the railway signal.
  • a beacon could be positioned at a distance of 200 meters from the specific railway signal (in case of a method meant for use at low train velocities as stated above).
  • a receiver in the train receives a signal from the beacon, as a result of which appropiate means aboard of the train start establishing the radio contact with the specific railway signal.
  • the beacon sends information to the train based upon which the radio contact with the specific railway signal is established.
  • the train establishes the radio contact with the the appropiate railway signal, and not with another railway signal (for example when there are a number of railway tracks extending alongside each other each being provided with their own railway signals).
  • the radio contact may have a limited range, such that there is no risk that a radio contact is established with another railway signal alongside the same railway track.
  • the information specifies the railway signal by means of a property of the radio contact, such as a frequency at which a contact with the specific railway signal can be established.
  • a property of the radio contact such as a frequency at which a contact with the specific railway signal can be established.
  • the beacon informs appropiate means within the train (such as, for example, a radio modem) about the frequency at which a radio contact with the specific railway signal can be established.
  • the safe functioning of the method may be improved further when along with the mode also an identification of the specific railway signal is transmitted to the train. As a result the establishment of a radio contact with a wrong railway signal can be prevented even better.
  • the automated braking of the train is stopped when, after initiation of such an automated braking, the mode of the railway signal changes to a mode not requiring a braking of the train. Then the train driver again gains control over the train (and, if desired, may initiate an acceleration of the train again).
  • the radio contact between the train and the railway signal is stopped when the train reaches a predetermined position relative to the railway signal. It should be noted, that preferably the radio contact, after being established, is maintained when the mode of the railway signal requires a braking of the train, and that the mode of the railway signal is thereafter monitored continuously by the train. Such monitoring, however, is no longer required and useless when the train has reached a certain position (generally close to the specific railway signal). When at the establishment of the first radio contact the mode of the railway signal does not require the braking of the train, the radio contact may be stopped immediately.
  • the radio contact is stopped by a beacon positioned at said predetermined position, such as a beacon positioned at a short distance ahead of the railway signal (in the above referenced low speed situation for example a few meters ahead of the railway signal).
  • the radio contact comprises a coded radio contact.
  • the present invention relates to an assembly for securing a train travelling along a railway track provided with railway signs, comprising means for establishing a radio contact between the train and a specific railway signal which the train is approaching and for transmitting a mode of the railway signal to the train; means for determining whether a braking of the train is initiated by the driver of the train when the mode of the railway signal requires such a braking of the train; and means for initiating an automated braking of the train when, in such a case, no braking is initiated by the train driver.
  • the assembly further comprises a beacon positioned alongside the railway track at a predetermined distance ahead of the railway signal for initiating the establishment of the radio contact between the train and the railway signal.
  • the beacon is devised for sending information to the train based upon which the radio contact with the specific railway signal is established.
  • the risk of establishing a radio contact with a different railway signal can be reduced in this manner.
  • further means are provided for stopping the radio contact between the train and the railway signal when the train reaches a predetermined position relative to the railway signal, such as, for example, a beacon positioned at a predetermined position.
  • the beacon is positioned at a short distance ahead of the railway signal.
  • a section 1 of a railway track is represented.
  • this figure shows a railway sign 2 positioned alongside the railway track.
  • the railway sign 2 is a sign comprising signalling lights with different colours (e.g. red, yellow and green).
  • the railway sign by means of its signalling lights informs the driver of an arriving train 3 about the status of railway track sections ahead of the present railway track section 1 (for example whether or not a preceeding train is present in said railway track sections). Based upon said information the driver will take an appropiate action (for example slowing down or completely stopping the train).
  • the present invention provides a method and assembly for ensuring that the appropriate action of the train (e.g. slowing down or stopping) will occur automatically also when the driver of the train does not respond correctly to the railway sign.
  • the appropriate action of the train e.g. slowing down or stopping
  • a first beacon 4 is positioned alongside the railway track section 1 at a predetermined distance (e.g. 200 meters) ahead of the railway sign 2.
  • a radiomodem (not illustrated in detail) aboard the train about a scanning frequency for establishing a radio contact between said radiomodem and the railway sign 2.
  • the radiomodem contacts the railway sign 2 which, in turn, will transmit information about its mode (red light, yellow light or green light) to the train.
  • the railway sign 2 also transmits an identification of itself to the train, such that the radiomodem knows that it communicates with the correct railway sign.
  • the information received by the train 3 indicates that the railway sign has red light, and it is determined (by appropriate means not shown in detail) that the driver does not react correspondingly by slowing down/stopping the train, an automated slowing down of the train 3 will be initiated by appropriate control means (not illustrated). The driver then cannot control the train himself.
  • the radiomodem While the train keeps on moving during slowing down, the radiomodem maintains its radio contact with the railway sign 2 and keeps on scanning the mode thereof. If the mode changes (for example to green light) an appropriate respons in the train will follow (for example the slowing down will end and the driver again gains control over the train 3). The radio contact can be ended then. When the mode does not change, the operation of the radiomodem also will continue.
  • a second beacon 5 is positioned in the vicinity of the railway sign 2, for example 6 meters ahead of it. When the train passes this second beacon 5, latter will contact the radiomodem aboard the train 3 and will stop the operation thereof.
