This is actually the case, VIC Rail has one of the largest PRIVATE networks in
the state. Their fibres run along the majority of the lines in the state.

The timetable booths are actually EXTENSIONS on PABX's (mostly NEC 7400
systems) that are routed to an IVR system with a set of predefined dialed
digits to allow the particular station to get the correct information. This is
usually set up as a speed dial. This is all very common equipment and readily
available. The "calls" that these booths are making are actually free to VIC
rail because of this routing.

They are also routing data (security cams, ticket machines, validation
machines etc) along these fibres to a central location.

Anyone who wants further info on their telecomms/data network layout can feel
free to mail me off list.
