7. Guard shall keep a sharp look out in the rear and be prepared to exhibit a hand danger signal to prevent the approach of a train from the rear and to protect if necessary.
8. When a train is stopped in the block section, on account of accident, failure, obstruction or other exceptional cause and the train cannot proceed, it shall be protected by placing three detonators at a distance of 250 – 250 and 10 meters apart from the train on the way out.
9. No train shall be backed. In unavoidable circumstances, it shall be backed only after placing three detonators at a distance of 250 – 250 and 10 meters apart in the rear of the point up to which the train is to be backed.

If the signal is not taken ‘Off’ within 10 minutes and if the detention is likely to exceed 10 minutes, train shall be protected in the rear by placing three detonators at a distance of 250 – 250 and 10 meters apart, and Loco Pilot shall send his assistant to the station / cabin to inform the fact that the train is waiting at the signal for its admission into the station.
12. After the train being admitted into the station by taking ‘Off’ the signals, the Loco Pilot shall make over the authority to the SM.
13. Trains must continue to work on this system until anyone of the means of communications is restored by the competent authority.
14. A record of all trains passed over during the period shall be maintained on the TSRs at both the stations concerned.
15. As soon as anyone of the means of communication has been restored, the SMs must send messages under exchange of Private Numbers and Line clear shall not be obtained or given until both the SMs are satisfied that all trains dispatched from their stations have arrived complete at the other stations. SCOR shall be intimated about this.
16. All the records in connection with the working of trains during the course of TIC shall be inspected by the TI of the section, who shall prepare a report on the working of trains and shall forward the same along with his report to the DRM within 7 days of communication.
