Real-time Train Location Tracking on Indian Railways

Indian Railways in association with ISRO, will soon launch real-time tracking of the trains using GPS devices. The information will be used for avoiding collisions, train scheduling and also for helping passengers to know the exact train location for their travel planning.

The Centre for Railway Information Systems (CRIS) in association with ISRO has developed a GPS-based solution which can provide exact location of a train with an accuracy of 10 metres, and latency of 2 minutes, on a real-time basis. ISRO’s INSAT-3C satellite will aid in location of moving trains.

The GPS devices would be fitted in about 100 trains, enabling the trains to know each other’s location and thus avoiding collision. The GPS application is also expected to aid in better planning of train schedules, especially in bad weather.

CRIS has integrated the GPS app with Google Maps, making the real-time location available to passengers as well, on their mobile or computer.

The facility to track train movements will soon be available on the Indian railway website at
