New Delhi, India: The Centre for Railway Information Systems (CRIS), the technology arm of the Indian Railways, developed a GPS-based solution with help of Indian Space Research Organization (ISRO), which can provide exact location of trains with an accuracy of 10 metres, and latency of 2 minutes, on a real-time basis. ISRO’s INSAT-3C satellite will help in determining the location of these moving trains.
The GPS devices, which will cost around INR 70,000-1,00,000 per train, would be fitted in about 100 trains, which may help avert collisions and prevent loss of lives. Speaking to an Indian daily, V A Chopra, MD CRIS said, “The government’s focus is to reduce the number of accidents and installation of real-time monitoring service on all trains by the end of 2013, which would contribute in improving the monitoring.”
Passengers may also be available to see real-time locations, as CRIS has integrated the GPS app with Google maps. The GPS system can give an accuracy of about 10 metres, with a lag of about 2 minutes.
Success of the GPS-based system may help Indian Railways in running trains at high speed. The GPS application will also aid in better planning of train schedules, especially in bad weather.
Currently, scheduling is done manually. Station masters call the divisional headquarters and inform them once a train has left a particular station. “In future, the controller will only plan the running and scheduling of trains instead of co-ordinating with various other stations to confirm the status of the trains,” added Chopra.
Indian Railways has about 77 control offices at over 6,000 stations. A pilot project has already started between Chennai and Tambaram railway stations, where about 364 suburban train services have been scheduled successfully with the GPS devices. CRIS plans to allocate around INR 70 crore to the project.
