An attempt at 2007 Question 8:
(untimed, open book)
"List the key advantages and disadvantages of axle counters, single and double rail track circuits for train detection.
A railway administration is going to provide axle counters and needs to define the rules and system requirements for managing miscounts and failures of the axle counter equipment. Describe the issues to be considered and appropriate control measures.
What issues need to be considered for the management of engineering work in axle counter areas, particularly where rail-road plant is being used?"
I expect I've somewhat mis-directed my answer towards "what Network Rail Standards mandate" rather than discussing the issues at a principle level.
