Most complicated journey

["Ronald BESDANSKY" <ronbest@bigpond.com>]

I'm looking for the most complicated, devious journeys by a train between
two points. For example, in NSW:

12/05/1984: Single-deck interurban special pass. from Helensburgh to
Liverpool via Circular Quay, Canterbury, Chullora Jns and Villawood

07/04/1968: Sydney Central-Gosford via Bankstown, Flemington Middle Jn and
Epping (steam).

One could include journeys which involved reversing at a junction station,
e.g.

15/09/1984: Parkes to Dubbo via Stockinbingal & Cowra (special pass. using
"Comet" set.)

Any other contenders?
