Sydney Trains is the operator of suburban and intercity rail services centred on the Sydney rail network. Sydney Trains is owned and operated by Transport for NSW, a statutory authority of the Government of New South Wales.

The Sydney Trains suburban network comprises nine lines with services extending as far as to the east, to the north, Richmond to the northwest, to the west, to the southwest, and to the south with some peak hour services continuing to Helensburgh.

Most of the Sydney Trains suburban network lies on the surface, though lines within and around the Sydney CBD run underground. The network is served by a fleet of double-deck electric multiple units.
