Abstract
The present invention relates to a system for aiding the movement of work trains on a railway line under construction having two tracks that are adjacent and two-way, managed from a central block PC by a PC chief. The system comprises a computer with means of management and of processing of data and an operation block diagram panel, means of communication between the PC chief and escort agents of the work trains for authorization requests to move in section, means of locating a train, connected to the computer, means of detecting the direction of travel of a train, connected to the computer, and means of entering the state of work of the sectors, connected to the computer. The system saves time by enabling a work train to move, under certain conditions, at the speed of the line.
Claims15
A method of aiding the movement of work trains on a railway line under construction having two tracks that are adjacent and two-way, and that is managed from a central block PC by a PC chief, comprising:
- a) dividing the tracks into sectors, extending between two end blocks, on which the trains can move in section or in work mode;
- and
- b) at a request for authorization from an escort agent of a train to the PC chief to move in section in one direction on a given sector,
- i) making a check as to whether another train is moving on the sector in question,
- ii) making a check as to whether another train is moving on the following sector in the opposite direction,
- iii) making a check as to whether the adjacent sector of the adjacent track is undergoing work and, if the three checks are negative,
- iv) giving authorization by the PC chief to the escort agent to move his train in section.
A system of aiding the movement of work trains on a railway line under construction having two tracks that are adjacent and two-way, wherein the tracks are divided into sectors, each of which extends between two end blocks, and on which the trains can move in section or in work mode, and wherein the railway line under construction is managed from a central block PC by a PC chief, system comprising:
- a) a computer at a central block, comprising
- i) means of management and means of processing of data;
- and
- ii) a block diagram panel for operating the line under construction, wherein the block diagram panel has at least the line's tracks, sectors and end blocks;
- b) means of communication between the PC chief and escort agents of the work trains for authorization requests, from an escort agent of a train to the PC chief to move in section in one direction on a given sector;
- c) means of storing messages;
- d) means of locating a train on the sectors of the line, wherein said means are connected to the computer;
- e) means of detecting the direction of travel of a train on the sectors of the line, wherein said means are connected to the computer;
- f) means of entering the state of work of the sectors, wherein said means are connected to the computer;
- and
- g) processing means for processing the data from the means of detecting and the means of locating so that, if
- i) no other train is moving on a sector in question,
- ii) no other train is moving on the following sector in the opposite direction, and
- iii) the adjacent sector of the sector of
- the adjacent track is not in works mode, the PC chief authorizes the escort agent of a train to move in sections on the sector in question from one end block of the sector to the other end block of the sector.
