Hi tfc82, I'm also attempting mod 1 this year so I would defer to the more experienced, however I suggest a good concept for part 2i) might involve a signaller giving erroneous permission to a user worked crossing user (where the uwc is not interlocked with the Signalling system) or another scenario may be a failure to spot a pedestrian or vehicle in a crossing area and initiate the crossing clear function (for an MCB or MCB CCTV).
Part 2ii) My thoughts were thinking Clapham and uninsulated wiring within locations providing false energisation of circuits, or failure to undertake a line clear verification correctly for an axle counter section (with a trolley or debris on the line).
