CEL has developed this system, in association with Research, Designs and Standards Organisation (RDSO) for providing early warning of the approach of a train/locomotive at an unmanned level crossing, to the people and road traffic crossing the Railway line.

Far end System of the Solar Powered Railway Level
Crossing Radio warning System (SOLAGARD)

The Level Crossing Warning System (SOLAGARD^TM) is suitable for use on Single as well as on Double lines, for providing Audio & Visual Alarms at the Gate through VHF Radio Communication Link Activated by the approaching train when it is on approach at a preset distance range of 2 to 5 kms. from the gate. This system operates on its own captive power supply consisting of Solar Photovoltaic Modules and Low Maintenance type batteries of suitable ampere hour capacity.

A track device actuated solar powered VHF transmitter located about 3-4 kms. from the level crossing (i.e. Far End) sends a coded radio signal towards the level crossing when an approaching train crosses the Far End. The radio signal is received by a solar powered receiver located at the level crossing (Gate End) which after decoding the signal actuates an Audio-Visual Alarm for forewarning the traffic. The system is ideal for remote railway level crossings. The ruggedized system is under field trials.

FEATURES :

• It uses a VHF link to activate an Audio Visual Alarm by an approaching train.
• It uses Solar Photovoltaic Power source for charging the batteries.
• It uses specially designed solid state logic circuits with very low power consumption and high MTBF (Mean Time Between Failures).
• It uses specially designed electro-magnetic Track devices for the detection of approaching train.
