Shunting Flashcards
What is a Shunter?
A Shunter is a person competent to control specific shunting movements in and out of a depot, a yard, or sidings.
What must you do when given instructions by a Shunter?
You must work to the instructions you are given.
What happens when you are signalled from the main line?
The controlling signaller will clear the appropriate signal to take you onto the reception road or direct to a siding.
What should you do at a stop board?
At a stop board, you must stop and wait for instruction.
What should you do at a position light signal?
At a position light, you must obey the aspect.
How does a panel operator communicate with your cab?
The panel operator will have radio contact with your cab and will give details of the move before clearing the signal.
What are facing points?
Facing points are where you face a diverging route.
What are trailing points?
Trailing points are where you face a converging route.
What are motorised points?
Motorised points allow for points to be controlled remotely.
What are trap points?
Trap points prevent wrong direction movement onto a running line thus derailing the train instead.
What are catch points?
Catch points prevent the rolling back of a unit into a section, i.e. if they become uncoupled.
What are spring points?
Spring points allow trains arriving on the curved ‘branch’ line to join the ‘main’ line. The points may be briefly opened by the train’s wheels, but ‘spring back’ as the train passes.
What are some risks found in a depot?
Some risks that can be found in a depot include: connections to the train, points that are not flush, derailers activated, scotches still present, trains standing foul of your movement, movements taking place within a building have the warning alarms activated, any signals for your movement are cleared, people working on or too close to the train, doors not fully open on sheds, and not to be moved boards present with tags.
What must be clearly received and understood before any move takes place?
The authority to move.
What should be checked to ensure safe movement of the train?
That the train can be moved safely.
What must be clearly understood regarding the move?
Where the move can be made to (the limits of the move).
What should you identify to ensure safety during a move?
All potential risks to avoid them.
What are some signalling methods for shunting?
Hand signals, shunting signals, fixed aspect signals, position light signals, semaphore shunt signals, disc shunting signals, limit of shunt signals.
What is used for communication on the railway during shunting?
Radio is used for a lot of communication on the railway.
What should be adopted to identify radio users during shunting?
Call signs should be adopted to identify the correct radio users involved in each shunting movement.
What must be maintained during shunting?
Constant communication must be maintained throughout the whole time that the movement is in progress.
What should you do if there is a break in transmission during shunting?
You need to stop your train and only restart when communication is re-established.
