Q. Explain about Overhauling of Level xing?

Each level crossing except those laid with PSC sleepers must be opened out and the condition of sleepers and fittings, rails and fastenings inspected at least once a year or more frequently, as warranted by conditions. However, level crossings laid with PSC sleepers should be overhauled with each cycle of machine packing or more frequently as warranted by conditions and in no case shall opening be delayed by more than two years. In all cases, rails and fastenings in contact with the road shall be thoroughly cleaned with wire brush and a coat of coal tar/anti-corrosive paint applied. Flange way clearances, cross level, gauge and alignment should be checked and corrected as necessary, and the track packed thoroughly before reopening the level crossing for road traffic.
