i. If the mid-section semi-automatic signal becomes defective and/or shows ‘RED’
aspect due to any reason, the Loco Pilot will contact the Station Master of the
receiving station ahead on telephone provided at the mid-section semi-automatic
signal post and inform him about the same and proceed ahead on getting the
verbal authority to pass signal at danger with private number of the Station
Master which he will record in his working diary.
ii. In case the telephone provided at mid-section semi-automatic signal is not
working or is not available and the Loco Pilot cannot contact the Station Master
of the station ahead by secured means of communication and the signal
continues to display ‘RED’ aspect, the Loco Pilot shall, after waiting for 5
minutes, pass the mid-section semi-automatic signal at ‘ON’ and proceed ahead
with great caution at a restricted speed not exceeding 8 kmph and be prepared to
stop adequately short of any obstruction on the track including a train ahead, till
he reaches the foot of the next automatic signal and be guided by the aspect of
this automatic signal.
(d) Failure of Fog Switch.
In case after taking action as per para 4 above by the respective Station Masters,
‘A/AG’ marker on mid-section semi-automatic signal does not get extinguished, fog
Signalling system shall be taken to have failed in between the two relevant stations
(in case ‘A/AG’ marker of Advanced and Home signals cannot be extinguished by
operation of the fog switch, the Station Masters will extinguish the ‘A/AG’ marker by
means of facility available on the VDU/Panel). In such a case, the Station Master of
the train dispatching station will not dispatch a train in the section until the previous
train has arrived complete at the receiving station which shall be confirmed by the
exchange of private numbers. In case the modified automatic Signalling system fails
any time due to any reason after the same has been introduced, the station master of
the train dispatching station will not dispatch a train in the section until the previous
train has arrived complete at the receiving station which shall be confirmed by the
exchange of private numbers.
9. During the change over from normal automatic Signalling to modified automatic
Signalling, it may so happen that a Loco Pilot may encounter a situation when the
‘A/AG’ marker gets extinguished and aspect of the signal turns into ‘ON’ aspect while
approaching any of the semi-automatic signals. In such a situation the Loco Pilot will
stop his train and inform the Station Master of the nearest station on Walkie-Talkie/CUG
etc. and proceed cautiously ahead till the foot of the next automatic signal and be guided
by the aspect of this signal.
10. At the time of introducing the modified automatic Signalling, the Station Masters
concerned controlling the mid-section semi-automatic signal should, as far as possible,
take care that the aspect of this signal is ‘ON’ to avoid sudden braking by the Loco Pilot
of the approaching train. In addition, the Advanced Starter and the Home Signal shall
normally be put in manual mode before introducing the changeover.
