Where can you find details of all line speeds
Table A diagrams in the sectional appendix
What does a standard speed board look like
Red circle, white background with black speed number (mph)
Red circle, black background with white speed numbers (kmh)
What does a reduction in speed warning sign look like
Upside down triangle, yellow border
White background black speed number (mph)
Black background white speed number (kmh)
What is the length of a speed restriction
The length of the restriction plus the length of your train
What do tilting train speed boards look like
Either red circle, yellow background with black speed number across the middle and EPS at the top
Or yellow sign with black speed numbers and EPS at the top
What do speed boards referring to diverging junctions look like
Standard speed board with arrow pointing the direction of the junction
What is the set up of a speed reduction indicator
AWS magnet 180 metres before the speed warning board.
Then suitable braking distance before the speed commencement board
If a speed warning board has two sets of numbers on it, one above the other. What does each number mean
The highest number will be at the bottom and relate to passenger trains, parcel and postal trains and light locomotive.
The lower number at the top relates to all other trains
Some permissible speed boards relate to different train categories and will have the code marked on the board. These are
HST = high speed train
MU = multiple unit trains
DMU = diesel multiple units
EMU = electric multiple units
SP = sprinter
What do temporary speed restriction warning board look like
Yellow board with black speed numbers and yellow board across the bottom, sticking out either side with two white reflective circles (normal)
If the yellow board across the bottom is the same width as the side this indicates limited clearance
Where can details on temporary speed restrictions be found
Published in the WON’s
What does TSR stand for
Temporary Speed Restriction
What does a temporary speed indicator commencement board look like
Yellow square with black speed number on it
What does a temporary speed termination board look like
Yellow rectangle with a black T in the middle
Or
Yellow rectangle with black A in the middle (acceleration board)
What is the basic set up for a temporary speed restriction
AWS magnet 180 metres before the TSR warning board, then suitable braking distance (can vary depending on traction, speed reduction, gradient etc)
TSR commencement board
Speed restricted Track
TSR termination board
What does S.P.A.T.E stand for
Speed Previously Advised Terminated Early
What does a SPATE board look like
Yellow rectangle with black diagonal line across
If a TSR is terminated before the published time where will the SPATE boards be placed
Over the TSR warning and commencement boards
When can a AWS magnet be placed nearer then 180 metres
When there is no suitable place around the 180 metres mark due to infrastructure or other AWS magnets
What’s the minimum distance from a warning board you can place an AWS magnet
45 metres
What must you do if you notice any incorrectly placed, missing or more restrictive TSR warning or commencement indicators
Report it to the signaller immediately, stopping your train to do so if required
