Rules Week 2 Flashcards
What does SPAD stand for
Signal passed at danger
What does SOYSPAD stand for?
Starting on a yellow, signal passed at danger.
What does SASSPAD stand for?
Starting against a signal, signal passed at danger
What does AWS stand for?
Automatic warning system.
When must you set the DRA?
1, When entering or leaving the cab.
2, When taking over from another driver.
3, When your train is stopped at a signal at danger.
4, stopped at a station platform where the starting signal is at danger.
5, Under absolute block at station platform, if distant signal had been passed at caution. You must set DRA, even if the home signal is displaying a proceed aspect.
6, Train stopped at station platform with no starter signal. When passed a single yellow or caution semaphore
What does DSD stand for?
What does DVD stand for?
Which does what?
Driver safety device - pedal (dead man’s)
Driver vigilance device - bleeper
What are the DSD & DVD used for?
They provide protection against the driver becoming incapacitated by applying the train brakes if the pedal is released.
The DVD pedal is the means of resetting the DSD alarm.
What must you do if the DSD is released, or the vigilance is not acknowledged in time?
1, Allow train to come to a stand
2, Secure the train. Brake to full service, set DRA, DDS to Neutral.
3, Check that brake was not applied by TPWS, pass command activation, the guard , or train division
4, Report the brake application to the signaller. Informing them that is was caused by DSD/DVD if you are sure this is the case
5, proceed ONLY when authorised by the signaller. Carry out any instructions.
6, Upon restarting if AWS sunflower is black and yellow, assume next signal Is at danger until it is visible and can confirm a proceed aspect is showing.
When should the DSD and/or DVD be treated as defective?
1, The vigilance alarm is sounding with the DSD depressed
2, The vigilance alarm cannot be cancelled by releasing and re-depressing the pedal
3, The train brakes cannot be released with the DSD pedal depressed and all other causes have been ruled out.
4, It is not possible to operate the pedal. (Pedal is stuck)
Who has the authority to isolate the DSD/DVD?
GWR maintenance control.
What are the speed restrictions when the DSD/DVD are isolated
1, AWS/TPWS - working, Competent person - available, Visibility- good?
2, AWS/TPWS - Working, Competent person - not available, Visibility - good?
3, AWS/TPWS - working, Competent person - not available, Visibility - poor?
4, AWS/TPWS - not working, Competent person - available, Visibility - good?
5, AWS/TPWS - not working, Competent person - available, Visibility - poor?
6, AWS/TPWS - not working, Competent person - not available, Visibility - good or poor?
1, No restriction
2, Max 60 mph
3, Max 40mph
4, Max 60mph
5, Max 40 mph
6, Do not move
What is the purpose of the DRA?
Inhibits traction power to prevent the driver from moving the train against a signal at danger.
When would you reset the DRA, when entering the driving cab?
1, The platform starting signal has been cleared.
2, you have been given authority to pass the signal at danger.
3, You are allowed to pass the signal at danger on your own authority.
When would you reset the DRA, when train stopped at a signal at danger?
1, the signal has cleared
2, You have been given authority to pass the signal at danger.
3, You are allowed to pass the signal at danger on your own authority.
When would you reset the DRA, when train stopped at a signal at danger at a station platform?
1, The signal has been cleared
2, You have been given authority to pass the signal at danger
3, You are allowed to pass the signal at danger on your own authority.
When would you reset the DRA, when train stopped at an Absolute block starting signal at a station platform?
Under AB, if a distant signal has been passed at caution, the DRA must be reset when the starting signal has cleared and the ‘ready to start’ signal has been given by the guard.
What is a splitting distant signal? And how must it be interpreted?
A splitting distant signal is used to tell the driver which way the train is going to be signalled at a junction, where there is one diverging route.
Always follow the least restrictive aspect.
What does TPWS stand for?
Train protection warning system.
What can be found in the Sectional appendix?
Routes
When will a TPWS brake activation take place?
1, a TPWS signal is passed at danger without authority
2, The train approaches a TPWS fitted signal at danger too quickly.
3, The train approaches a TPWS fitted reduction in linespeed to quickly
4, The train approaches TPWS fitted buffer stops too quickly (max 8mph)
5, Fail to cancel AWS in time.
What is the ‘minimum’ position of safety for-
1, 0-100 mph
2, 101-125 mph
1, 1.25 meters
2, 2 meters
What is a milepost used for?
Distance marker.
Gives milage to London.
Every line/dot is the equivalent of a 1/4 of a mile or 80 chains
What distance must be kept from OLE equipment?
2.75 meters
What voltage runs through the CRE (3rd tail)
650-750 volts DC
