Different types of signboards are installed from the railway station to the railway track. Very few people know the meaning of these signboards. There is a board on the side of the railway track on which W/L (सी/फा) is written. This board is often seen while passing around the crossing.
The full form of this W/L is Whistle/Level (सीटी बजाओ/फाटक). This board is installed at such a place where there is a crossing. It is installed 600 meters before the level crossing. This signal board alerts the loco pilot to sound the horn. It is mandatory to blow a horn while passing through here.
