Q

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)

A

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

17
Q

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)

A

You must be sure, or get assurance from the person in charge, that:

  • 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

18
Q

What are the 3 additional precautions required for passenger carrying trains on goods loops? (TS1 / Reg 11.3)

A

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

19
Q

What is the definition of a goods line? (Glossary)

A

A line that has not been signalled to the standard required for running passenger trains

20
Q

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)

A

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

21
Q

What must we do if there is an obstruction within the overlap? (TS2 / Reg 4.1.3)

A

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

22
Q

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)

A

You must instruct the driver to remain at a stand, regardless of aspect, until authorised by you

23
Q

What must you do if another signaller is involved with an obstruction of the line? (TS2 / Reg 4.2)

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

25
Q

When can you allow a train into a section with a line obstruction? (TS2 / Reg 4.3)

A

(WADE)

You must not allow a train into the affected signal section until the line is clear and safe for the passage of trains unless it is necessary to:

  • Work to and from the point of obstruction, or serve an intermediate station or siding, but only if this can be done safely
  • Allow an assisting train into an occupied section
  • allow a train to pass through a Diverging junction before reaching the obstruction
  • Examine the line
26
Q

Train an unusually long time in section (TS1 Reg 21)

If you become aware that a long time has passed after a train has entered a section, you must try to contact the driver to find out the cause
