Can you give me some hints how to answer that question?
Thank you
Question 2
Describe a suitable methodology for ensuring that the risk resulting from reducing the overlap length beyond a signal, on a railway which is not fitted with an automatic train protection system, remains tolerable?
Illustrate your answer with a diagram showing the inputs and outputs to and from the process.
Bear in mind that I never did module 7, but the first part looks to me like a question that could be worded "describe a risk assessment process with which you are familiar and use it to identify risks arising from ... [insert text from question above]... The second part appears to narrow down the sort of risk assessment process a bit and this is where I start to get on shaky ground, but I think there is a quantified risk assessment process that has a tree structure and assigns probabilities to the events and hence allows a numerical calculation of the possible outcomes. In fact a quick web search on "Quantified Risk Assessment" brings up things like this from the IET. That is how I would go about it.
If he is around, Bigcheese might have a better idea than me.
