Looks like fun - I still haven't covered a considerable amount of the Sydney Suburban system but unfortunately I'm working on Friday - Perhaps if anyone does another of these with a bit more notice, I might take annual leave. I wouldn't mind doing something like this.
Apologies for that, Brendan. The date was flagged in a different thread but you would have had to be reading it, in a lengthy post.
There will be another event, The Great Sydney Train Race, during civilised hours on Monday January 13th, where the game will be to bag all 10 of the stations that will be randomly drawn from the hat on the day. A family event, should be done by late afternoon.
As for the All Stations Challenge, the next running will be advertised on the Facebook group (linked above).
