The rail network is
extensive and is operated
by CityRail. The central
area is served by double-decker
electric trains which
pass through the city
and terminate in various
suburbs, or run round
the underground city
loop and return to their
origins. Longer, medium-distance,
services start in Sydney
Central station and make
only limited stops in
the suburbs.
If you just want to make
a return rail journey,
suburban or medium-distance,
there are off-peak returns
available after 9.00am
at discounted prices.
Such tickets are available
at any time at weekends.
Several other special
types of ticket are available
too, for which see the
section headed “tickets”.
