The Grinkle Signalman will then be able to restore the ordinary Tablet
working between Staithes and Grinkle.
- When the train is ready to leave the Mines Sidings, the Guard must act
as follows :—
1.—Telephone Grinkle Signalman that the train is ready to leave. If
not ready to depart direct, say how long the movements are
likely to occupy. The Signalman will then give the necessary'
instructions for the return journey. (The occupation key cannot
be withdrawn from the Occupation Instrument if a Tablet is out
of either instrument).

Grinkle, the Guard must turn the key until No. 2 appears, and •
wait until the word " FREE " appears above, he must then
turn the key until No. 3 appears, when he can withdraw the
Occupation Key.

the Main Line, and after restoring the points and locking the
frame and box, the Occupation Key and the key of the Ground
Frame box must be handed to the driver, who will proceed to
Grinkle, and deliver the keys to the Signalman there.
If the Occupation Instruments either at Grinkle or the Ground Frame
fail, the Guard •must obtain instructions on the telephone from the Station
Master or Signalman at Grinkle as to what course is to be adopted.
If a failure of the telephonic communication between the Ground Frame
and Grinkle occurs and the Guard is unable to carry out these instructions,
he must, unless he can communicate with Grinkle by telephone from the
boulby Mines Office, at once dispose of the train and proceed with engine
to Grinkle, taking with him the Occupation Key, and advise the Signalman
verbally that the points are locked in the normal position. He must then
hand the key to the Signalman at Grinkle in order that the tablet working
may be carried on.
If, however, the key is locked in the Occupation 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. (O. 6532).
