Shildon Tunnel—Continued.
9.--In case there should be any defect in the block instruments, the
trains must be signalled by telephone until the defect is rectified. Should
the telephone be also out of order the traffic must be worked by a pilotman
in accordance with General Rules 227 to .239, an engine being provided
which he must make use of when necessary.
10.—For the purpose of repairing the lines through the tunnel the Up
line will be closed between 3-30 a.m. and 7-30 a.m. on week-days, except on
Mondays, when it will be closed from 3-0 a.m. to 6-0 a.m. Should, however,
the platelayers have completed their inspection before 6-0 a.m. on Mondays,
or before 7-30 a.m. on other days, the ordinary working must be resumed
after the instructions for resuming ordinary working have been complied
with. The platelayers must not enter the tunnel until their Foreman has
ascertained from the Signalmen at the respective ends of the tunnel that
the Up line has been blocked ; and the Up line must be blocked in accordance
with regulation 15 of the Block Telegraph Regulations before the foreman
is so informed. The signalman at the North end must not inform the
foreman platelayer that the line has been blocked until he has seen that the
indicator is pegged to train on line. The line must be kept blocked until
the foreman in charge of the platelayers has reported to the respective signalmen
that the whole of the men under his care have come out of the tunnel
and the line is clear, and on this being done ordinary working may be resumed.
When the Tunnel South box is opened before ordinary working is resumed
the signalman there must, before switching into circuit, peg the Up line
block indicator to the train on lino position, and he must then carry out the
instructions as given when resuming ordinary working. The foreman platelayer
must report to the signalman at Tunnel South box when that box is
open, and to Shildon Junction box when the former is closed. During the
time the platelayers are in the tunnel repairing the lines they must use
proper means to protect themselves, as trains will occasionally be passing
on the Down line.
During the time that the Up line through the tunnel is blocked, i.e., from
3-30 a.m. to 7-30 a.m. on weekdays, except Mondays, and from 3-0 a.m.
to 6-0 a.m. on Mondays, a platelayers' trolley may be allowed to run a short
distance on the Up Facing line towards Fieldon Bridge in order to tip refuse,
but before this is done the signal " Blocking Back Outside Home Signal"
(3 pause 3) niust be given to and acknowledged by the signalman at Fieldon
Bridge box, in accordance with Recording Telegraph Regulation No. 7.
The indicator must remain in the " Train on Line " position until the
signalman at Tunnel North is informed by the Foreman platelayer that the
line is again clear. The Down Main line at Tunnel North must not be
obstructed by the trolley until the signalman's authority has been obtained
for this to be done. ( O . 5422).
