How steep are the grades do you think/know are in central station's flying junctions?There is a modern track document, in colour, with all the Sydney region track features marked, including gradients, as it has been mentioned in other threads. I once downloaded it when someone posted the URL so it is a public URL, but I must have deleted it as I can not find it now.
