HOT WEATHER PATROLLING
Period for hot weather patrolling shall be laid down by the Chief Engineer for each section and patrol charts prepared where necessary. Patrolling shall be organised by PWI accordingly. In addition, the PWI/PWM and the Gangmate shall be vigilant during summer and on hot days. Hot weather patrolling will also be introduced, when the rail temperature rises above td+25 degree Centigrade
1. Hot weather patrolling will be carried out as follows:-
i) On single line or where only one road in a double line section is having LWR / CWR - One patrolman for 2 km.
ii) On double line section when LWR/CWR exist on both roads - One patrolman for 1 km length of UP and DN road. The beats of each hot weather patrolman will thus be restricted to 2 km.
2. The hot weather patrolman should always carry the following equipments:- HS Flags - Red 2 Staff for Flags 1 Detonators 10 Canne-a-boule 1
3. Duties of hot weather patrolman are as follows:-
He will walk over his beat slowly over one rail in one direction and on the other rail in the return direction. On double lines, he will repeat this procedure alternately on UP and DN tracks. He will be vigilant and look out for kinks in the rail especially during the hottest part of the days.
When a kink is observed, he shall immediately examine at least 100 sleepers ahead and in the rear of the kink for any floating condition of track. He should meticulously sound each and every sleeper, 100 sleepers on either side of the kink, to determine any floating condition.
The sounding will be done by dropping a canne-a-boule on each end of the sleeper to determine the extent of void under the sleeper. Should the sounding reveal a floating condition, under which a buckle may be anticipated or the patrolman has detected actual buckling of track, he will take immediate steps to protect the affected portion by display of hand signals as per rules in force. After protecting the track, the patrolman will arrange to advise the Gangmate, PWM, PWI of his apprehension of a buckle/actual
