What is a CV and what is its purpose?
Carre violet. A CV is to protect dangerous points e.g. level crossing, points etc
How must a driver proceed on secondary tracks?
- Marche a vue - The driver of a train movement is obliged to proceed with caution, controlling his speed, taking into account the line advance, such that it is possible to stop short of: any train, stop signal or obstacle. Obey shunting instructions. Including by radio. And not exceed 30 kmh.
- Obey immediately and without question all orders given by signals
- Slow down in the event of bad visibility.
- Maintain an interest in signals even when passing them.
- Inform RCC controller of any incident or malfunction of equipment that may have an impact on train movements or safety.
- Conform to instructions given by RCC.
What are the 3 illuminations of a CV, what do they mean?
- Constant white light. The signal is open.
- Constant violet light. The signal is closed.
- Flashing white light. The signal is open for a limited movement.
What are the two types of CV?
Dwarf and high level
What should a driver do at a closed CV?
Stop before the signal and secure the train with 1.5 bar depression in the CG. Contact the RCC and let them know your location and await instructions.
A CV is open what should the driver do?
Know the movements to be carried out and proceed in March a cue.
A CV is showing a flashing white light, what are the drivers responsibilities?
- Know what your train movements are
- proceed in marche a vue but be prepared to stop before a closed CV.
- Forbid movement onto main tracks.
What are the hand danger signals, by day and night?
- By day (except in a tunnel) unfurled red flag, red and white chequered board, both hands above head.
- By night and in tunnel, a red light from a hand lamp. A red light on a chequered board.
- ****Red means stop!!****
Garage. Indicates that the movement is directed toward secondary tracks. Proceed in March a cue.
Indicates movement towards a dead end track. Proceed in march a vue.
Proceed in march prudente and not exceed 15kmh. Be prepared to sound your horn to warn road users of your movement. Stop immediately if the track is obstructed.
- Neutral zone.
- Shut of tractive effort.
- Manually open VCB1/2 before the corresponding loco reaches the signal.
End of neutral zone. Manually close VCB after passing the relevant signal. Resume tractive effort.
- Lower pantograph signal.
- Cut traction power before loco reaches signal. Press emergency pant down button.
- Check catenary power showing on VDU.
- Press pant 2 button.
- reapply traction.
- End of pantograph restriction.
- As soon as head of loco passes this signal press the emergent panto down button. check no catenary power showing on VDU. Press panto 1 button, reapply traction. When you can be sure the rear loco has passed raise pant 2.
State the two typos of signalling?
- Main line - cab signalling
- Secondary line - lateral signalling
What is a section of track between two reperes called and how long is it?
What are the two types of data sent to the TVM (cab signalling)?
- Continuos data - generated by a frequency modulated track circuit.
- Intermittent data - Track side loops that send information. e.g. sec, uplift stop etc.
When a zero indication is presented in the cab you approach a signal with a proceed light on. What are your actions.
- I confirm the proceed light is on.
- I cross the section marker.
- Observe the cab signalling.
When a zero indication is presented in the cab you approach a signal.What are your actions.
- I stop in a rear of the marker and secure the train with a 1.5 bar depression in the CG.
- I make myself know to the RCC by pressing the SG button.
- I conform the the RCC instructions or the cab signalling (other than a zero or a red)
What are the 4 ways you can pass a marker on a main line?
- Cab signalling (TVM)
- A white proceed light
- Verbal FREP
How do you pass through a neutral section?
- Sec distance board - check on the cab desk that sec 1 illuminates.
- Open smily face board - vcb1 opens and illuminates
- Tractive power goes
- Closed smiley face - vcb1 closes and extinguishes
Name the 5 cab signalling control systems?
- TVM channel (Z CAB)
- Maximum speed imposed by the TVM (Z KV)
- Maximum speed without TVM (L LIMit VIT)
- Engagement of the pantograph uplift stop (Z BP)
- Crossing of the neutral section (Z DJ)
What does Z KV do?
Isolates the over speed facility, requires the driver to press the yellow ATP when an audible warning is sounded to indicate a speed change.
What does Z CAB do?
- Allows you to isolate the cab TVM.
- Either channel A or B
- Or both channels together
- Or run normally
What does Z LIMIT VIT do?
- Isolates the speed control that is set to 30 kph when in there is no display on the TVM. Only works when on secondary track when you have no TVM.
- Ie. When you are on a secondary track and have no TVM when Z LIMIT VIT is active it will apply emergency brakes when you go above 30kph. When this is isolated there is nothing to stop you doing this. Proceed in Marche a Vue.
What dies Z DJ do?
Isolates the control for the automatic neutral section. When isolated you will have to manually pass through a neutral section.
What does Z BP do?
Isolates the automatic uplift stop.
What is the purpose of Z Escab?
It carries out a cab signal test.
When you see the CAB board what should you do?
Continue in MAV. Within the next 200m cab signalling should return to the TVM. If does not then apply emergency brakes.
How can you proceed when the BPFC button is flashing?
With a FREP
What should your actions be when entering secondary tracks marked with G and CAB with a line through it?
- Proceed in MAV from the G board.
- Check the lights on the TVM are extinguished within 200m. If not manually disarm.
- Obey the trackside signals.
If your TVM shows 000 and there is an illuminated proceed light on the next maker what should you do?
- Pass through that marker at MAV and expect to stop before the next marker
- Expect reds to be shown
When would you continue moving when you had 3 reds shown?
- When you pass a closed marker (after getting Frep, Frep fv or proceed light) in MAV. the next section may turn red due to.
- Broken rail
- faulty equipment
- Section occupied by previous train
- ZEP activated
- You know that you are safe to continue to the next marker as you have had authorisation and are in MAV so therefore expecting reds.
What is the BPFC button for?
Its the signal override button that turns of the train safety system that would activate the emergency brake. Allows you to pass a marker when Reds or Zeros indicated. Must be stationary to activate it.
What should you do if you overrun a closed CV and measures to resume running?
- Emergency stop - lower pantos
- EM call to RCC
- Warning light
- Hand danger signal
- Ask RCC authorisation to raise pantos
- use application instructions
- To resume act as if you where in rear of CV. Fill in FREP. Move off in MAV or follow TVM.
What do you do when presented with an abnormal signal?
- In the case of a CV, treat it as closed.
- For other signals treat as if they were showing there most restrictive access
- If st davids cross present then treat as if not there
What are the track parity's in the tunnels and the terminals?
- Both terminals - 2
- tunnel 1 - 1
- tunnel 2 - 2
- When exiting secondary tracks in France - 2
- when exiting secondary tracks UK - 1
What should the driver do in the event of absence of CAB signalling?
- treat it as reds and perform emergency stop
- Inform RCC
How do you pass a closed marker with no FV, extinguished proceed light or no proceed light?
- Driver to use application instructions
- override the sections automatic braking function by pressing the BPFC button.
- If FREP gives authority to pass multiple markers due to know faults driver needs to stop in rear of each one to activate BPFC button.
What is the purpose of the speed control and what will its activation cause?
- To stop the train when the current speed of the train exceeds the authorised speed
- Causes a cut in tractive power.
- Emergency braking
- Illumination of the SURV indicator
What are the drivers actions in the event of a SURV when speed is exceeded?
- Confirm the emergency brakes
- Put the power controller into the zero position
- Wait for the Surv light indicator light extinguishes
- Release the automatic brake
- Resume the traction
- Be doubly careful when observing the speed
What are the drivers actions in the event of a SURV when speed is not exceeded?
- Confirm the emergency brake
- Put the power controller to zero position
- Wait for the train to stop
- Advise the RCC
- Use the application instructions
If you need to isolate speed control Z KV what do you need to do and what will happen if you don't?
- You will need to acknowledge the audible beep of changes of speed by pressing yellow atp button within 2 seconds.
- Failure to do so will activate FURS and force and emergent brake until stationary.
What is the only way you can verbally be told to stop?
- The RCC may call on t to t and say train no..... Emergency stop.
- Driver must perform emergency stop
- conform to RCC instructions
- Receive a verbal order to resume the movement
You are driving on a secondary track. When approaching the CV showing a white proceed light, you see that the signal closes inadvertently. What actions would you carry out? From the moment when you realise that you can't stop short of the signal and that you are going to foul the points situated in advance?
- I carry out an emergency braking
- i lower the pantogrphs
- i emit the warning light signal
- i send a priority radio call by pressing EM on t2t or orange button on CR.
- I present a hand danger signal to the train movements that may be coming
- I advise the RCC
- I wait on the spot for a permission from the RCC to pass (FREP)
- I ask the RCC for authorisation to raise pantographs
You are driving on main tracks and the cab signalling visual display extinguishes. What are your actions?
- I carry out an emergency brake
- I lower the pantographs
- I advise RCC
- I ask permission to raise pantographs.
- Having stopped I refer to the application instructions
You are driving on the main tracks outside the tunnel and you notice the flashing of the front lights of a train coming the other direction.
What does this mean and what do you do?
- This is a warning light
- I carry out and emergency stop
- I lower the pantographs
- I request instructions from the RCC
- I ask for permission from the RCC to raise pantographs
- I conform to their instructions
