===Suburban rail===
Sydney, Melbourne, Brisbane, Perth and Adelaide have extensive suburban rail networks which have grown and expanded over time. Australian suburban rail typically operates with bidirectional all-day services with Sydney, Melbourne, and to a lesser extent Perth and Brisbane's systems operating with much higher frequencies, particularly in their underground cores. [[Sydney Trains]] operates the busiest system in the country with approximately 1 million trips per day. [[Metro Trains Melbourne]] operates a larger system albeit with a lower number of trips.
