98
Q

When can you authorise a signal to be passed at danger?

A
  • The signal is defective or disconnected
  • The signal cannot be cleared because signalling or level crossing equipment has failed
  • For shunting purposes, a main aspect or stop signal is to be passed at danger when there is no associated position0light or semaphore shunting signal
  • The signal cannot be cleared because a train or movement which has reversed is then required to start from beyond that signal
  • An elective train is to pass the signal protecting an isolated section and proceed towards the limiting point
  • In an emergency, and then only when authorised by the signal box supervisor or Operations Control, on a TCB a signal is to be passed, so that a train carrying passengers can enter an occupied section to use a station platform. (in an emergency, and then only when authorised by the signal box supervisor or operation control to allow emergency permissive working).

An Engineering train is to:
- Move towards a possession or,
- Leave a line under possession at an intermediate point.
A train is to pass the signal protecting engineering work under the requirements of module TS1 General Signalling Regulations, regulation 13.2 to gain access to:
- A station where the train is required to start back
- A line under single line working
- A siding

The line is to be examined to check that is is clear.
A train is to enter the section to:
- assist a failed train,
- evaluate passengers from a failed train
- Remove a portion of a divided train
- Remove train or vehicles that have proceeded without authority
Single line working applies
Working by Pilotman or modified working applies

Q

When you have a defective main aspect signal a river can approach the signal, if?

A

104
Q

When you have a defective main aspect signal a river can approach the signal, if?

107
Q

Describe a ‘complex’ points failure?

A

A failure of power operated points that needs more point ends to be set or secured (or both) than a simple failure. It includes all failures that affect switch diamonds or swing nose crossings
