DETONATING SIGNALS Detonating signals otherwise known as detonators or fog signals are appliances, which are fixed on the rails, and when an Engine (or vehicle) passes over them, they explode with a loud sound so as to attract the attention of the Driver.
DETONATING SIGNALS … Care and Custody– • Detonators should be protected against dampness. They should be stored in tin cases with papers wrapped over them, a layer of waste cotton must be kept at bottom and top of the tin cases to avoid contact with the metal. • In one tin case not more than ten detonators should be kept.
DETONATING SIGNALS … Care and Custody– • The tin cases should be stored in wooden boxes which should be kept in dry places and not left in contact with the brick walls, damp wood, chloride of lime or other disinfectants; these should not be exposed to steam or other vapours. • Unexploded detonators should not be, as far as possible, sent from place to place by consignment; they should be conveyed personally or by a messenger.
DETONATING SIGNALS … Stock with Engineering Official– • Each P. Way, Works and Bridge Engineer shall have a stock of detonators sufficient to recoup the number annually tested any which may be exploded for works and emergency. The SSE/P. Way (In-charge) shall ensure that all Gangs, Gatemen, Keymen, Patrolmen and Watchmen are equipped with the specified number of detonators.
DETONATING SIGNALS … Stock with Engineering Official– • Every ADEN, Gangmate, Keyman, Gateman, Patrolman and Watchman, whose duties include protection of track shall carry the specified stock of detonators with him on duty, for use during an emergency.
DETONATING SIGNALS … Stock with Engineering Official– • The month and year of manufacture are shown on the label outside each case and also stamped on each detonator. • Detonators should be used in the order of the dates stamped on them, the oldest being used first. To facilitate ready withdrawal in this sequence, they should be stored also accordingly.
DETONATING SIGNALS … Use of Detonators– • The staff in possession of detonators shall not make any improper use of them. All Engineers are responsible to ensure that the staff working under them know how and when to use detonators. • A detonator when required to be used shall be placed on the rail with the label or brand facing upwards and shall be fixed to the rail by bending the clasps around the head of the rail.
DETONATING SIGNALS … Use of Detonators– (during emergency) • Whenever in consequence of an obstruction of a line or for any other reason it is necessary for a railway servant to stop approaching train • He shall plant a danger signal at the spot and proceed with all haste in the direction of an approaching train with a danger signal (red flag by day and red light by night), • To a point 600 m from the obstruction and place 1 detonator on the line,
DETONATING SIGNALS … Use of Detonators– (during emergency) • After which he shall proceed further for not less than 1200 m from the obstruction and place 3 detonators on the line 10 m apart. • He should then take a stand at a place not less than 45 m from there, from where he can obtain a good view of an approaching train and continue to exhibit the danger signal, until recalled. • If recalled, he shall leave on the line 3 detonators and on his way back pick up the intermediate detonator continuing to show the danger signal.
DETONATING SIGNALS … • Use of Detonators– (during emergency) • On single line the line must be protected on each side of obstruction. • Where there adjacent lines and it is necessary to protect such lines, action should be taken on each such line in a similar manner.
G & SR PARA 6. 03(1)(I)(H) (h) Should any train be seen approaching, the person going to protect the train shall immediately place one detonator on the line, as far away from the disabled train/track as possible and will continue to show his hand danger signal to stop any approaching train. If the person has already placed one detonator on 600 or 400 m in BG or MG/NG respectively and he is not in a position to reach at a distance of 1200 m or 800 m in BG or MG/NG respectively, he will again place one detonator as far away from the train which has met the accident.

LIFE OF DETONATORS • The normal life of detonators is 5 years. • The life of the detonators can be extended to 8 years on a yearly basis subject to the condition that 2 detonators from each lot of over 5 year old ones are tested for their effectiveness as discussed above and the results being found satisfactory. Such time extended detonators can be used on all sections after satisfactory testing. • In case the results are not satisfactory, they should be destroyed. • In any case, no detonator should be kept in use after 8 years.
DISPOSAL OF TIME-BARRED DETONATORS • No detonator that bears any sign of rust and is time- barred shall be held in stock. • Such detonators shall be destroyed by one of the following methods (i) By soaking them in light mineral oil for 48 hours and then throwing them one by one into fire with due precautions. (ii) By burning them in incinerator. (iii) By detonating them under wagon during shunting operations. (iv) By throwing them in deep sea.
DISPOSAL OF TIME-BARRED DETONATORS … • The destruction of time-barred detonators should be done in the presence of a JE/SSE (P. Way) who should ensure that every care is taken to see that splinters of detonators do not cause any injury to life and property. • They should not be buried or thrown in places from where they could be recovered.
SAFETY RANGE • When detonators are being tested/being placed in case of emergency, no person should be allowed within a radius of 45 metres from the detonators to be exploded; the engine crew shall remain well within the cab. In practice, splinters from detonators when exploded seldom fly in a direction to the rear of the wheel, which detonates them. Staff should therefore, when observing the safety radius, place themselves, as far as possible on the rear side.
FOG SIGNALS Procedure for placing detonators during fog: • SM shall send two trained railway servants i. e. , Pointsman / Track maintainer to act as Fog signal men, one in either direction with 20 detonators to the Fog Signal Posts which are erected at 270 m in rear of First Stop signal. • Each of these Fog signal man shall proceed speedily to the respective Fog signal post(FSP) and place two detonators 10 m apart from each other on the centre of the head of the rail, with the label or brand upwards, which shall be securely fastened to the rail by bending the clasps round the upper flanges of the rail, which on explosion under the wheels of an engine, will warn the Loco Pilot of his proximity to the Outer / Home signal of the station as the case may be.
FOG SIGNALS … Procedure for placing detonators during fog: • SM shall not grant Line Clear unless he receives information on walkie-talkie from Fog signal man that detonators have been placed at the FSP. In case of no intimation from Fog signalman due to walkie-talkie not being available or out of order etc. , Station Master can grant Line Clear for the first train after a time lapse of 30 minutes from the departure of Fog signalman.
FOG SIGNALS … Procedure for placing detonators during fog: • After placing detonators on the line, the Fog signal man shall withdraw beyond the safety radius of 45 m from the detonators before they are exploded by an approaching engine or train. He shall warn any other persons in the vicinity of the safety radius to keep away. Staff while observing the safety radius of 45 m shall place themselves as far as possible in rear of the locomotive, train or wagon passing over the detonators.
FOG SIGNALS … Procedure for placing detonators during fog: • After passage of each train, over the detonating (fog) signals, which have been so placed on the rails, the Fog signal man shall immediately replace them by two fresh detonators. • On single line sections, for trains leaving the station, the Fog signal man deputed to place detonators shall show to the Loco Pilot a proceed hand signal (PHS).
FOG SIGNALS … Procedure for placing detonators during fog: • Each of the trained Fog signal men sent out with detonating (fog) signals, shall carry a flashing hand signal lamp. If the Fog signal man is aware of any obstruction on the line, he shall show a Stop hand signal in the direction in which a train is expected or approaching.
FOG SIGNALS … Procedure for placing detonators during fog: • DRM will notify the names of stations at which fog prevails persistently. At each such station, two Pointsmen and two Track maintainer shall be nominated to act as Fog signal men. All four men shall be fully trained in fog signalling duties.

MULTI SPEED RESTRICTION (I. E. EXISTENCE OF TWO OR MORE THAN TWO SPEED RESTRICTIONS IN CONTINUATION) …. In case of following speed restriction being more restrictive, a minimum of 200 m track should be under earlier speed restriction zone. If not, then only one SR board should be provided, considering that the previous speed restriction is at par with the following SR, which is more restrictive.
Multi Speed Restriction RETRO REFLECTIVE TYPE BOARDS - TO BE PROVIDED IN NEW CONSTRUCTION AND DURING REPLACEMENT OF EXISTING BOARDS
Works of Long Duration Multi Speed Restriction, when s₂ < s₁ To be located at a distance equal to the length of the longest passenger train operating on the section concerned Place of work 30 m 800 m 30 m Speed restricted zone of 45 kmph Speed restricted zone of 20 kmph To be located at a distance equal to the length of the longest Goods train operating on the section concerned
MULTI SPEED RESTRICTION (I. E. EXISTENCE OF TWO OR MORE THAN TWO SPEED RESTRICTIONS IN CONTINUATION) …. In case of following speed restriction being less restrictive, corresponding speed indicator board for following speed restriction shall be placed at a distance equal to the length of the longest goods train operating on the section after termination point of previous speed restriction zone.
MULTI SPEED RESTRICTION

PROTECTION ARRANGEMENT DURING EMERGENCY • Whenever in consequence of an obstruction of a line or for any other reason it is necessary for a railway servant to stop approaching train • He shall plant a danger signal at the spot and proceed with all haste in the direction of an approaching train with a danger signal (red flag by day and red light by night), • To a point 600 m from the obstruction and place 1 detonator on the line,
PROTECTION ARRANGEMENT DURING EMERGENCY • After which he shall proceed further for not less than 1200 m from the obstruction and place 3 detonators on the line 10 m apart. • He should then take a stand at a place not less than 45 m from there, from where he can obtain a good view of an approaching train and continue to exhibit the danger signal, until recalled. • If recalled, he shall leave on the line 3 detonators and on his way back pick up the intermediate detonator continuing to show the danger signal.
PROTECTION ARRANGEMENT DURING EMERGENCY • On single line the line must be protected on each side of obstruction. • Where there adjacent lines and it is necessary to protect such lines, action should be taken on each such line in a similar manner.
