In a bid to provide real-time train information, the government plans to install GPS devices on 2700 electric locomotives by December 2018.
As reported by BGR, a written reply to the Lok Sabha by Rajen Gohain, Minister of State for Railways, stated that the Railway Ministry and ISRO have collaborated to install Real-Time Train Information System (RTIS) to track trains.
This involves placing GPS/GAGAN (GPS Aided Augmented Navigation System) based devices on locomotives.
Gohain added that Phase-1 of the project would cover 2,700 locomotives, all installed with the GPS devices by December 2018. He also mentioned that a reliable and high-level accuracy of about 99.3% of real-time reporting of arrival and departure timing updates have been observed, which is good enough to meet RTIS requirements.
Real-time GPS information is an excellent tool for the purpose of adhering to a tight schedule and avoiding delays.
