A

Service breaking distance is the area between the first restrictive signal and the stop signal. This is set to allow trains to stop safely and comfortably under normal braking.
4 aspect - double yellow to red
3 aspect - single yellow to red

Q

What is permissive working?
How would you be signalled into a platform under permissive working in both absolute block and colour light signalling?

A

Permissive working, allows one or more trains into a section

Permissive working is allowed in
* signal
* block
* dead end platform areas as mentioned in the sectional appendix.

Coloured light.
You will be authorised into a platform, working permissively by an associated position. Light
(note, main aspect will remain at danger.)

Semaphore :

Q

What does DSD stand for and what is it’s purpose?

A

Drivers Safety Device
Also know as dead man’s handle

42
Q

The rule book states 16 reasons to pass a signal at danger with authority from the signaller - list 5

A

Think 🤔

P A S S E S
R E D
S I G N A L
& Check line

P - pilotman or modified working applies
A - assist a failed train / evacuate passengers from a failed train
S - shunting purposes, a main aspect or stop signal is to be passed at danger when there is no associated position-light or semaphore shunting signal, or an EoA passed when it is not possible to issue an MA.
E - ERTMS equipment is defective or disconnected and is preventing an MA from being issued.
S - starting beyond the signal (The signal cannot be cleared because a train or movement which has reversed is then required to start ahead)

R - remove a portion of a divided train / remove a train or vehicles that have proceeded without authority.
E - electric train is to pass the signal or EoA protecting an isolated section and proceed towards the limiting point.
D - defective or disconnected signal

S - section signal cannot be cleared. (A train has been accepted using restricted acceptance because the line is clear only up to the home signal of the next signal box)
I - In an emergency, and then only when authorised by the signal box supervisor or Operations Control, on a TCB or ERTMS line a signal or EoA is to be passed, so that a train carrying passengers can enter an occupied section to use a station platform.
G - gain access to:
* a station where the train is required to start back
* a line under single line working
* a siding.
N - no authority - A train is to enter the section after:
* a train or vehicle that has proceeded without authority has been removed, or
* the front portion of a divided train has passed through the section.
A - engineering train is to:
* move towards a possession, or
* leave a line under possession at an intermediate point.
* engineering train is to move towards a protection zone.
L - level crossing equipment has failed and signal cannot be cleared
S - Single line working applies

  1. The line is to be examined to check that it clear
43
Q

Who can authorise a driver to pass a signal at danger?

A

Driver
Shunter
Hand-signaller
Pilot-man
Any person mentioned in the rule book

44
Q

What are the drivers actions for passing a signal at danger with authority?

A

Reset DRA
TPWS override
Proceed at caution
15mph over points/crossings
Follow all instruction given by signaller

45
Q

What signal can drivers pass at danger on their own authority and under what circumstances?

A

Control signal - when the driver can confirm the signal box is closed and only when the driver has exhausted all means of contacting the signaller.

46
Q

What precautions must be made through the section after passing a signal at danger on your own authority?

A

Proceed at caution - expect the line to be occupied
15mph over points/crossings
Only pass through a tunnel if you know it is definitely clear and at 10mph
Stop at the next stop signal and try to contact the signaller.

47
Q

What are the areas on the WON

A

A - temp speed
B - engineering works
C - signalling (permanent way)
D - other notes / anything else

48
Q

Speeds with a DSD failure?
