The F50 used to also do a WLM-BNE-OOL-WLM trip towards the end as well. I think back in the old days too the F27 used to go to Moree before Eastern took it over.
Never had a ride on the F27 but had one on the F50, was a nice machine to ride on. Eastwest used to do SYD-NLK in a F27 before the F28, now thats long haul !
