The manual mentions that some trains are to be worked under Manual Block Working procedures due to them not reliably operating track circuits (speaking of which, what is it about Australian track circuits that a light engine or even two or three of them together (!) will not operate them reliably?) and anybody interested in further details should have a look at Network Rule 'NSY 512'. Having done that, a question poses itself: According to that document, basic block working applies between a controlled signal and another controlled signal (or a nominated location). That makes sense, because you need to prevent a following train from entering that block section before you've confirmed it clear by alternative means. However in that case how is e.g. the included 2011 timetable supposed to work out?

That's interesting, I'm not sure why D423 has that comment applied. You definitely don't have to block work a pair of 81s unless they traverse the areas highlighted in this image, taken from the Train Operating Conditions manual. I'll ask the timetable writer if there's a reason.

Mantis 38519 - description is incorrect, definitely a non block working movement. Thanks for that
