PROVISION OF LINESIDE SIGNALS
This document defines the mandatory requirements for the provision of lineside signals and the sequences in which signals aspects shall be presented to the drivers, in respect of plain line, diverging junctions and for the bi-directional lines.
PROVISION OF STOP SIGNALS
PROVISION OF STOP SIGNALS – 1
A stop signal that controls a running direction movement along or onto a running line shall be a main signal except that it is permissible for a shunting signal to be provided for the control of other than timetabled passenger train movements.
A stop signal controlling movement into or along siding shall be a shunting signal, unless other considerations require it to be a position light aspect on a main signal.
PROVISION OF STOP SIGNALS – 2
- Block Signalling
In all forms of fixed block working, the entrance and exit of every signal section shall be denoted by a stop signal.
PROVISION OF STOP SIGNALS – 3
4. Facing Junctions:- A stop signal shall be provided on every line on which signalled movements can approach facing points, with the exception of train operated points
PROVISION OF STOP SIGNALS -4
- Ground Frames :- Signals on running lines protecting ground frames shall be controlled signal designated non passable.
PROVISION OF STOP SIGNALS -5
- Level crossing :- Where level crossing is required to be protected by interlocked signals, a stop signal shall be provided on every line on which signalled movements approach the crossing.
PROVISION OF STOP SIGNALS -6
- Conflicting Movements :- A stop signal shall be provided on line on which signalled movement can approach an area of conflict, including trailing points and other items of infrastructure including moveable bridges.
- Lockout Systems :- Where a lockout system for the protection of trackside personnel is provided, a stop signal shall be provided on every line on which signalled movements can approach the area protected by the lockout system .
- Signals at Point of Reversal :- Where trains are required to reverse on lines worked by track circuit block or absolute block, a stop signal shall be provided at the point of reversal to authorize the movement in the reverse direction
