No sign of signalling yet.
If there is it must be deliberately hidden.
The Belair line can't start without it.
I will be able to almost shake hands with the Millswood loop on Saturday so will report then.
The Belair line platform at Goodwood was still a major construction zone when I went past a few days ago, especially around the big gap where it was demolished for the Brownhill Creek culvert, and doesn't look fit for service. If the line reopens in the next week or two I would guess the trains would not stop there, and on a "passengers for Goodwood use front car only" basis if they did.
My guess is that the notices to staff about the line resuming from July 1 were an each way bet on the line being ready, and that Torrens Transit were also told to be prepared for substitute bus operation to be extended. I would say that the complete silence from Adelaide Metro to the public indicates it is not likely to be opening next week, if they had that good news ready I can't see any reason that they would withhold it.
A technical question though - I know that the Millswood loop being in service is necessary for the full timetable to be operated, but could the line be operated without any signals there if the points are locked out of use, kind of like the situation at Elizabeth? That could be useful for allowing a couple of test runs to be done on the section beyond Millswood while that signalling work is still pending, to scrub off the surface rust and check all the track circuits are functioning properly with the level crossings manned for safety and done one or two at a time.
