I've seen nothing around Adelaide yard that would require a big shutdown................

..........There is no reason to do a full shutdown to put up a few wires, politics has nothing to do with it.

I'm not sure whether electrifying the trackwork in Adelaide yard (platforms 1 - 4) counts as "putting up a few wires", but take your point.
But what about the signalling?   Isn't the signalling in the Adelaide yard still operating by track circuits, which will need replacing with axle counters before the wires are energized?  I'd imagine this will need some sort of shutdown to do this, especially with recent track-record of new signalling works on Belair & Noarlunga lines.
Also, with upcoming electrification to Dry Creek / Salisbury, will there need to be some sort of future shutdown on the Gawler line for the 25 kV-compatible signalling modifications over that section, even if the overhead wiring can be put up at night (as was mentioned during one of the govt. announcements).
