ISRO develops satellite based chips to alert users at unmanned railway crossings

ISRO has recently developed satellite-based chip systems which will alert road users at unmanned level crossings about approaching trains and also help in tracking train movement on a real-time basis.

On a trial basis, the Mumbai and Guwahati Rajdhani trains will be equipped with this system.
Road users will be warned by hooters if a train approaches an unmanned level crossing as railways are installing ISRO-developed integrated circuit (IC) chips on locomotives of trains. 

There will be hooters at 20 unmanned level crossings on Rajdhani routes for Guwahati and Mumbai, said a senior Railway Ministry official involved with the project.

More trains will be equipped with such technology in a phase-wise manner, according to the plan.

About 500 metres before the level crossings, the hooter will be activated through the IC chip, warning road users as well as the train driver near the crossing.

The hooter will be louder as the level crossing nears, and finally it will be silent after the train passes by.

Besides alerting road users, the satellite-based system will also be used for tracking trains for disseminating information about their movement on real time basis.

This will be of great help to passengers as currently train movements are tracked manually.
