What is the purpose of a junction indicator?
Where is a junction indicator located?
A junction indicator is provided to show that a train is being signalled to a route to the left or right of the straight route
A junction indicator is normally located above the signal, and will display a line of white lights when a proceed aspect is displayed
What does a route indicator display and what can they be associated with?
A route indicator will display either a letter or a number to show the route onto which the movement is being signalled
Route indicators may also be associated with a junction indicator
When do you test emergency alarms and indicators?

When can you allow a train carrying passengers to enter a goods line or goods loop? (TS1 / Reg 11.1)
- if the arrangements have been published
- in an emergency if authorised to do so by the signal box supervisor or Operations Control
When must you stop each train carrying passengers and tell the driver what is happening before allowing the train on to the goods line or goods loop? (TS1 / Reg 11.1)
Unless the arrangements have been published, you must stop each train carrying passengers and tell the driver what is happening before you allow the train on to the goods line or goods loop
What must you do before you allow a train carrying passengers onto a goods line or goods loop that is not protected by trap points from a movement from sidings? (TS1 / Reg 11.2)
You must be sure, or get assurance from the person in charge, that:
- these sidings are clear of vehicles and no movement will approach, or
- all vehicles and traction units on these sidings are properly secured and are clear of the line to be used by the train carrying passengers
If the driver of any traction unit is present, you must tell the driver, or be sure that the driver has been told, not to make any further movement until authorised by you
What are the 3 additional precautions required for passenger carrying trains on goods loops? (TS1 / Reg 11.3)
You must not allow a train carrying passengers to approach a stop signal or block marker on the goods line or goods loop unless the line is clear and the route is correctly set to the next stop signal or block marker beyond
You must keep all points in the correct position until the train has passed clear of those points or has stopped at the signal or block marker protecting those points
You must not allow another train to approach a stop signal or block marker if there is a train carrying passengers in the signal or block section beyond
What is the definition of a goods line? (Glossary)
A line that has not been signalled to the standard required for running passenger trains
What are the initial steps to take in the event of an obstruction of the line? (TS2 / Reg 4.1.1 and 4.1.2)
If you need to stop trains because of an obstruction or other emergency, you must place or keep at danger all signals necessary to protect the line
If necessary, you must arrange for train radio messages to be sent
If you cannot stop a train proceeding towards the obstruction or other emergency, you must carry out the instructions shown in TS2 / Reg 5
You must also place or keep any release, slot or acceptance switch in the normal position
What must we do if there is an obstruction within the overlap? (TS2 / Reg 4.1.3)
If the obstruction or other emergency is within the overlap of the protecting signal, you must place and keep at danger the previous signal that can be controlled to danger unless there are facing points that you have set for a route that is clear of the affected section
If a train is detained at a signal on the approach to the affected section (obstruction of the line) what must we do? (TS2 / Reg 4.1.4)
You must instruct the driver to remain at a stand, regardless of aspect, until authorised by you
What must you do if another signaller is involved with an obstruction of the line? (TS2 / Reg 4.2)
If another signaller controls the signal that will protect the obstruction or other emergency, you must immediately tell that signaller what is happening
If this signaller is in another box, you must first send the emergency alarm
What must you do if you receive an emergency alarm? (TS2 / Reg 4.2)
If you are the signaller receiving this message (obstruction of the line) or emergency alarm, you must carry out the instructions shown in TS2 Regs 4.1 and 4.3 (Stopping trains because of an emergency & Allowing a train into the affected section)
You must then tell the signaller giving you the message or emergency alarm whether you have been able to stop a train proceeding towards the obstruction or other emergency
