What's probably more complex about that is the requirement to move steamranger's turntable. You couldn't easily convert it to dual gauge and I cannot think of any convenient spots to put it off the top of my head, I imagine further up their mainline but space will still be a limited.Spotto wrote: ↑Wed Jan 12, 2022 10:53 pm1NEEDS2POST wrote: ↑Wed Jan 12, 2022 9:02 pmAren't there single track tunnels between Belair and Mount Barker?

I think that specific paragraph referred to the connection between Mt Barker Junction and Mt Barker station, unused for many years. They'd probably need to pull the entire track along that section and relay it from the ground up (and gauge convert while they're at it).
Another thing I have to add to the thread is that I took the Overland to Melbourne this past week (a great service) and it took an hour flat from Keswick Terminal to Mount Barker Junction. NR 21 and it's 7 carriages didn't make one stop, but I think anyone who thinks the existing alignment is any use for a commuter service is dead wrong.
