Maurie,

I think South Control operates both ends of the loop, prior to ARTC's take
over (in AN days), the Section from Keswick (including the station) to Dry
Creek North (maybe Salisbury) was operated by Dry Creek Cabin.

About a week before I left NRC last February, the signals and switches at
Keswick came under GSR control, the section to Dry Creek came under a
Metropolitan Controller (not Trans Adelaide) forgot his exact title, which I
assume was the former Signaller at Dry Creek Cabin? (sounded like the same
guy anyway).

The Signalling between Mile End and Dry Creek North (Salisbury) was worked
under ABS rules.

Things were changing that fast over there at the time it was hard to keep
up.

Regards,

Bob.
