Indian Railways and IIT-Kanpur developed the Real-Time Train Running Information System

A joint team of Indian railways and IIT-Kanpur developed the real-time train running information system, a technology which will help a mobile user to get the information about the exact location of a train. Under the new technology the user will have to type the train number and SMS it to 09415139139 or 09664139139 for getting the exact location of a train on real-time basis.
The satelite-based train tracking system was jointly developed by the Centre For Railway Information Systems (CRIS), the IT arm of Indian railways and Indian Institute of Technology (IIT), Kanpur to overcome the limitations of the existing Train Running Information System.

At present the real-time train running information system service covers 36 pairs of premier trains. Some of the trains which have been provided with the new technology include Mumbai Rajdhani, Howrah Rajdhani, Dibrugarh Rajdhani, Sealdah Duronto and Shatabdi trains for Bhopal, Kanpur and Amritsar.
The Indian Railway has allocated 121 crore rupees for the project and the service is likely to be extended to all major trains over the next 18 months. The Indian Railways has received the permission from the Indian Space Research Organisation (ISRO) to operate the system through its satellite. The railways department, however, sought fresh order from ISRO, to extend the facility to other major trains.
