Sydney-Brisbane rail corridor

The Sydney–Brisbane railway corridor is a standard gauge railway corridor that connects the state capitals of Brisbane and Sydney in Australia.

The corridor consists of the first 193 km of the Main North Line from Sydney Central Station to Maitland, and then the entire 795 km of the North Coast Line to Roma Street railway station, Brisbane.

The NSW TrainLink XPT passenger service operates along the route, as do a number of other freight and passenger services.

Originally the corridor was made up of the Queensland Rail narrow gauge Southern line and the New South Wales Government Railways standard gauge line that met at the inland town of Wallangarra at a break-of-gauge in 1888. It was not until 1930 that the coastal, standard gauge North Coast railway line was extended from Casino to Brisbane making through services possible, using a rail ferry for the river crossing in Grafton in New South Wales, until a bridge was opened in 1932.

The old Main North railway line which went to Wallangarra now terminates near Armidale.
