Wrong Direction Movements TW7 Flashcards
What makes a wrong-direction movement a wrong-direction movement? TW7-1.1 (1)
A wrong-direction movement is when there is no signal is provided (would just be a movement otherwise).
Under what circumstances may a wrong-direction movement only be authorised? TW7-1.1 (10)
A train is to return after overrunning a platform as long as the overrun is not more than 400 metres or 440 yards beyond the platform.
A train is to return after taking a wrong route at a junction.
A train is to make a movement to return from or proceed towards a line blocked by an accident, failure, obstruction, or other exceptional incident.
A train cannot continue forward and has to return because it has failed, or it cannot be driven from the cab at the leading end.
A light locomotive or multiple-unit train (loaded or empty) is to proceed over the affected or unaffected line to assist a failed train.
The front portion of a divided train is to return to the rear portion.
An engineering train is to move towards or from a line under possession.
A shunting movement is to be made through points that are worked from a ground frame.
Single line working is in operation.
A rail-grinding train is to return to extinguish a lineside fire.
Other than a Signaller, who can a Driver get authority from to make a wrong-direction movement? TW7-1.2 (2)
Pilotman or handsignaller acting on Signaller’s instructions.
If there is no cab at the leading end of the movement, when is the Driver allowed drive from another cab? TW7-1.2 (1)
As long as there’s a competent person available to control the movement.
Before authorising a wrong-direction movement, what must you make sure of to make sure the line is safe? TW7-2.1 (5)
Barriers or gates at any controlled level crossings are closed to road traffic.
Any AHBC without wrong-direction controls is locally operated.
All points are in the required position and locked by FPL (where provided).
Any unworked points are secured.
Any ground-frame release giving access to the route is ‘normal’ unless it needs to be operated for the movement.
Before the wrong-direction movement takes place, what distance must you make sure that the line is clear for, beyond the signal or place to which the movement is required to proceed, and what is the distance called? TW7-2.3 (2)
440 metres or 440 yards.
Clearance distance.
What must you not allow to happen in the distance that must be clear beyond the signal or place to which the movement is required to proceed, and what are the exceptions? TW7-2.3 (5)
No conflicting movements within the clearance distance.
Except if the movement is proceeding to a stationary train or vehicle.
Except if the movement is proceeding to the point of obstruction.
Except if the movement is proceeding to the detonators protecting a possession.
Except if the movement is proceeding beyond the point at which it will return to a line in the right direction.
What must you tell the Driver when instructing them about the wrong-direction movement? TW7-3 (6)
What is required.
How far the movement can go.
To check, where possible, that the points and crossings are set correctly for the movement.
That any unworked points have been secured.
To proceed at caution (except during SLW).
The arrangements at level crossings.
When can you move any points in the route involved for a wrong-direction movement, after a move has been authorised? TW7-4.1 (1
Until you are sure the movement has passed clear of any points or the track circuit controlling these points.
Unless fitted with wrong-direction controls, what must you tell the Driver when approaching an AHBC which is being locally controlled? TW7-4.2 (2)
Approach the crossing at caution and not pass over it until authorised by a green handsignal shown at the crossing.
What must a Driver do at all times when crossing over an ABCL? TW7-4.2 (2)
Driver must make sure it is safe to pass over.
Driver must sound the horn continuously until the front of their train is on the crossing.
How must a Driver approach a manned crossing and when can they pass over it? TW7-4.2 (2)
Approach the crossing at caution and not pass over until they are sure it is safe to do so.
How must Drivers drive their train during a wrong-direction movement, and what is the exception and the speed of the exception? TW7-4.3, S5-3.1 and S5-4.2 (2)
Caution; Drivers must always be able to stop within the distance they can see to be clear.
SLW; no greater than 50mph.
What must Drivers do with any AWS indications they receive during a wrong-direction movement? TW7-4.4 (1)
They must disregard the AWS indication and cancel any warning indication.
