Wrong Direction movements & Working in the Wrong Direction Flashcards
GERT8000
What is the Maximum speed during a Wrong-Direction movement?
50MPH (unless there is a more restrictive ESR in place).
What are the 4 reasons you do not need the 400m clearance distance for a wrong-direction movement?
The movement is proceeding:
to a stationary train or vehicle
to the point of obstruction
to the detonators protecting a possession
beyond the point at which it will return to a line in the right direction.
Over which lines would you use working in the wrong direction? (3 answers)
1) Unaffected line - to assist a failed train from the front.
2)Unaffected line to assist a failed train BEYOND a train cannot provide assistance (leap frog).
3) Affected line - towards a failed train where no crossover is available at the signal box immediately beyond the failed train (in the normal direction of travel).
What are the 12 reasons to allow a Wrong-Direction Movement?
Train has overrun a platform (by no more than 400m).
Train has taken a wrong route at a junction.
A train is to return from/towards a line blocked by accident, failure, obstruction or other exceptional incident.
A train cannot continue forwards due to failure, or the leading cab cannot be driven any more.
The front of a divided train is returning to the rear portion.
A Light loco (or MV) is to proceed over the unaffected or affected line to assist a failed train.
An engineering train is to move towards a line under Possession.
A shunting movement is to be made through points worked from a ground frame.
An OTM is to return to the published start mileage for work.
SLW applies.
An OTM/Engineering train is working in a PZ (Protection Zone).
A rail-grinding train is returning to put out a lineside fire.
What checks must you make before authorising a Wrong-Direction Movement?
Barriers at controlled crossings are closed to road traffic.
Protecting signals are at danger with Reminder Appliances (RA’s) applied.
Points are in required position and locked with FPL’s where provided and RA’s applied.
Any AHBC without wrong-direction controls have been taken under local control.
Ground Frames releases giving access to the route are at normal, unless required for the movement.
The portion of the line required is clear for the movement - with no conflicting movement authorised.
What must you tell drivers before authorising a wrong-direction movement?
What is required.
How far the movement will go.
To check points/crossings are correctly set for the movement (where possible).
That all un-worked points are secured.
The arrangements at any level crossings.
To proceed at caution.
Whose authority is required to use ‘Working in the Wrong Direction’?
SSM or Ops Control
What is working in the wrong direction?
It is a series of wrong direction movements made between more than one signal box’s area of control.
What bell code is associate with Working in the Wrong Direction?
3-3-2 bells
What is the clearance distance beyond the signal/location of the move, before authorising a wrong-direction movement?
400m
