Unmanned Railway Crossings

[sgpal@hotmail.com]

Indian Railways have 26 000 unmanned level crossings, where the road
buses and trucks have free access to cross the railway tracks, all the
time. There are frequent ugly accidents at the level crossings as the
road vehicle driver can not hear the whistle of the railway engine, due
to the masking effect of road vehicle diesel engine.
It may be possible to equip each level crossing with :
1. Two solar panels, one on either side of the track, about 1 Sq m
area; 2. Two Lead acide maintenance free batteries, fed directly by the
Solar panels;
3. A switch to start a flashing light to warn the road users about the
presence of a " Railway Crossing ", during the dusk hours;
Any suggestions to cut down the cost and to improve the reliability of
the system are welcome.    Dinesh Bansal, Chennai, India
