More trains will be equipped with such technology in a phase-wise manner, according to the plan.
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.
Safety at unmanned level crossings is a cause of serious concern for railways and the public transporter is exploring various ways to address the issue.
There are about 10,000 unmanned railway crossings in the country which account for around 40 per cent of accidents involving the railways.
While the Railways have eliminated 1,148 unmanned crossings in 2014-15 and 1,253 in 2015-16, it has scaled up its target and now plans to eliminate all such crossings in the next 2 to 3 years, the official said.
The satellite-based system will also help railways in mapping the area and the technology will come in handy at the time of accidents when it can be used to ascertain the exact location of trains and topography.
