You can't set back generally without permission of the signaller, normal procedure is the call the signaller request permission, change ends move back then change again that proceedure is followed. You can't go back if there is a train behind (there is one timetabled 5 minutes behind which can be only 300m at time)

Due to the track layout at GCD setting back is tricky as the overlap beyond the signal before GCD is 20m up the platform so setting back would set the signal at Lansdowne Rd to red thus possibly causing a SPAD incident thus requiring the signaller to take control.

The black box records distance, acceleration, braking, postion of the controller handle, antilock brake state and the ATP state it also records the door interlock state so it would be possible to prove an overshoot and that the doors opened. ITs based on establishing a datum point eg Lansdowne Rd stop. The box has a limited storage capacity and unless we have the coach number we are stuffed.

Yes this is a breech of safety

And yes uinlike IE they will write back

If I was on board I would have got out (I know what I am doing) and took the photo and opted for the walk to Pearse. Evidence is key coach number train composition, opinion on approach speed
