Special Instructions applicable at Particular Places.—Continued. 209
Working of Roseberry Mines Sidings, between Nunthorpe Junction
and Great Aytaa--Continued.
If, owing to the failure of the telephonic communication, the guard is
unable to carry out these instructions, he must at once dispose of the
train in the sidings and proceed cautiously with the engine to Great Ayton
Station, taking with him the tablet, and advise the signalman verbally that
the points are locked in the normal position. He must then hand the tablet
to the signalman in order that tablet working may be carried on.
If, however, the tablet is locked in the Intermediate Tablet Instrument,
he must proceed on foot and advise the signalman of this, and at the same
time inform him that the points are locked in the normal position.
If it be known that telephonic communication has failed before the train
leaves Nunthorpe Junction or Great Ayton Station, as the case may be, the
train must be detained until there is sufficient margin to make the journey
through the section, or to the Mines and back, without restoring tablet
communication. ( O . 4407).
