Emergency Special Working (ESW) Temporary Block Working (TBW) Flashcards
What is Emergency Special Working
A method of working that allows trains to move during signalling failure
Where can ESW be used
It only applies to double track lines fitted with Track Circuit Block regulations
What’s the difference between ESW and TBW
ESW driver communicates directly with the signaller,
No hand signaller, instead an ESW ticket is used
What does an “End of ESW” sign look like
Yellow sign with black EW diagonally crossed in red

Operate the TPWS temporary isolation switch
What speed must you go through the ESW section
50 mph max and 15 mph over points, crossings etc
What must you do at the end of ESW signal
Stop, there will be no hand signaller but should be a sign
Reinstate TPWS
Contact signaller, let them know you’ve arrived

Hand to the hand signaller
Tell guard
Reinstate TPWS
Watch hand signaller remove detonator
Hand signaller will either give you a yellow flag to proceed or the signaller may clear the signal
How must you proceed when leaving a TBW or ESW area
At caution, for as far as you can see the track to be clear at a speed obeying all further signals
What happens with AWS as you pass through a TBW or ESW area
You will still get the AWS warnings, acknowledge and disregard them
If you’re the lead driver in a tandem train what must you do when entering a TBW or ESW area
If TBW the hand signaller will take TBW ticket RT3184 and show it to the other driver
If ESW you must complete ESW ticket NR3190 and show it to the other driver
