Hort,
My point is that everything regarding the answer is an assumption and that it is entirely possibly the errant freight train has disabled some of the interlocking or its functionality; that there are sometimes simpler ways of achieving an end than a technical solution and that risk is not what kills people - it is the poor management or lack of attention to mitigation of risk that does.
M1 is about safety and the exam is about the student showing the examiner they understand the problems, issues and hazards. More marks are gained for depth of knowledge and preciseness. There is no time in the exam to discuss detailled risk analysis but stating pilot working is possible but would have an impact to the timetable plus adds additional (not necessarily worse) risks would show depth of knowledge.
I would argue about pilot working being "inherently riskier" than signalled working. However, I would be curious to hear your arguement to validate the point. If you do, I'll add my rebuttal and it would be a useful discussion for the forum I feel.
