The present invention relates to a novel train describer systenn for efficient traffic control in railways. Train describer is a system or group of devices connected together to indicate to the Railway Operator (eg. Train Traffic Controller / Stationmaster) the location and description of train (train number) in the area under his control.
In the system of operation in vogue in Railways, the traffic controller monitors the movement of train using telephone connection with the Station master and charts them manually on a distance time chart, also writing down the train numbers on their respective line on their graph. The stationmaster only knows which track of the station area is occupied in the station but not which train is occupying the track. More over the track occupancy at a station is not directly indicated to the traffic controller. Hence the traffic controller has to speak to the stationmaster and note down the occupancy position for controlling purpose.
To obviate such problems, we have come out with this state of the art system by which this novel train describer system will automatically display to the stationmaster and to the traffic controller the train number and the track in which it is occupied at a station and in between stations as well. This will enable better train traffic control. The system under our invention can be used as an add-on facility to make use of the existing automatic train control system together with existing Railway Optic fiber communication system and or GSM / GSM- R wireless radio communication or train control system communication network through balise or RFID. This information can also be used by public to track a train for their travel information.
Accordingly the present invention consists of a novel train describer system for railway traffic control adaptable to an automatic train control system comprising, interfacing equipment in the train onboard system (4) with associated communication network (15) (16) selected from GSM and GSM-R capable of transferring the location information to the interfacing

equipment available in ground station (20) as well as to the central processing unit (17) which is capable of processing the location information along with the input from the train interfacing equipment at station masters office (20) through a plurality of interfacing equipment and generate output data in an appropriate format transmittable to the display means located at railway station master's premises and traffic control room provided with display means.
Now the invention will be described in more detail with reference to the accompanying drawings, bringing out a number of embodiments of the arrangement according to the invention.

The automatic train control system takes its input from the interlocking equipment (2) through the line side electronic unit (3) and Ballses. The balise is the device used for communication between tracks and train and vice versa (in some cases). In other words, the Balise can be used for both way communications between tracks to train. One of the special advantages in the train describer system under our invention is its novel feature as an add-on facility on the core automatic train control system. In place of we can make use of RFID also. Now we will explain how the train describer system function.
When the train (4) passes over a balise / RFID (8), the information about the location of the balise /RFID (the coordinates) is transmitted to the on board equipment. This information together with the train identity, which the loco knows, is then transmitted to the central processing equipment (central server) (17) through any of the following methods,
a) Via a GSIM modem to the GSM network (15 and 16)
b) Via the balise / RFID (8), if it s a bidirectional balise / RFID to the Line side electronic unit (3) and then to interface equipment (20) at station and from the interface equipment (22, 21) via the optical fiber network to the central processing equipment (17) at control center.
c) Via GSM-R network if available as in (a) above.
Every time the train encounters a balise / RFID along different routes, the location information of the train is transmitted through any one of the communication networks.

When the train passes a balise/ RFID, the location information thus received from the train is then processed along with the route information available through the signal interlocking. This processed information is used to indicate the route that train will take at a station. As the train passes along the route, the track circuit occupancy information available at interlocking is also made use of to mark the progress of movement of the train along the route. The indicator/ display panel with LCD, LED or Video both at control center and at stationmaster's office can be mimicked regarding the train movement. It may be noted that the processing of information is done at the interface equipment (20) at station and then the display information is exchanged between control center and station. Alternatively, the route information and track occupancy information can be sent to central processing equipment (17) via the optical fiber network and processed by central processing equipment. Interfacing equipments is a data modulator-demodulator capable of working with GSM and GSM-R network.
Train describer can also provide accurate information regarding platform where the train is placed along with the train numbers & block occupancy to the stationmaster as well as to the train controller along with. Display. Requisite information tailor made to the convenience of the public can also be displayed in the platform.
In another embodiment under this invention the onboard equipment in the train can be provided with G.P.S. receiver, which would enable to display the location of the train in between two adjacent railway stations.
Although the invention has been described in considerable detail with particular reference to certain preferred embodiments thereof, variations and modifications can be effected within the spirit and scope of the invention as described herein above and as defined in the appended claims.
