South Coast railway line, Queensland

The South Coast line was an interurbancommuter railway line in South East Queensland. Operated by Queensland Railways, the line opened in 1889 and was later extended to the border with New South Wales. At its peak, the line ran for 111.7 kilometres (69 miles) from South Brisbane to Tweed Heads, serving the South Coast (now known as the Gold Coast). The Tweed Heads branch closed in 1961 and the line from Beenleigh to Southport closed in 1964.

In 1996, the Gold Coast line opened, running on a modified alignment in the north and a new route in the south. Since 2009, it has terminated at Varsity Lakes. There have been proposals to extend the present-day line to the Gold Coast Airport, which would result in three new stations in suburbs that were previously served by the South Coast line.
