The Murwillumbah railway line is a disused line in far north-eastern New South Wales, Australia. The line ran from Casino to Lismore, Byron Bay and Murwillumbah, and opened in 1894. It is one of only two branches off the North Coast line, (the other being the Dorrigo line). Services on the line were suspended in April 2004.
The first section opened between Lismore and Murwillumbah, connecting the Richmond and Tweed rivers. Passengers and goods were transported to Sydney by coastal shipping from Byron Bay. Nine years later, an extension from Lismore to Casino opened (and later south to Grafton - it was not until 1932 that the line was fully connected to Sydney). As early as 1889, feasibility talks took place into extending the line north from Murwillumbah into Queensland, discussions that continue to the present day. The line became a branch line when in 1930, the North Coast Line was extended from Kyogle to South Brisbane.
The North Coast Mail was the premier train between Murwillumbah and Sydney after the North Coast line was completed in the 1930s.
Additional local trains plied the tracks between Casino and Murwillumbah, connecting with other services such as the Brisbane Express and Brisbane Limited. The extension to Condong was for sugar mill traffic. 620/720 class railcars also worked this line (set 638/738, which was specially modified, and also hauled a small van). From 1973, the Gold Coast Motorail provided passenger and car transport between Sydney and Murwillumbah. In February 1990 the Gold Coast Motorail was replaced by an unnamed CountryLink XPT service.
