Just wondering why all the signals are bagged on the northern. I realise
its now running ATO but why not just disconnect the old signals entirely
so they're off?

I expect that is because a signal that is bagged is clearly
decommisioned (or not yet commisioned), but a signal that is unlit
is required to be treated as a red signal - becuase that's the safe
thing to do if the bulb blows.

Sure - if signals are still being used. But they're not and all the drivers
know it. Besides which if the train is on ATO what the driver thinks is
irrelevant because the train will just sail past anyway.
