Dajarra and Selwyn Branch Railways were lines in north-west Queensland, Australia. Along with the Mount Cuthbert and Dobbyn Branch Railways, they were essentially built to tap large deposits of copper discovered in the Cloncurry region.
The Dajarra branch ran from Malbon in a south-westerly direction to the small town of Dajarra. Its construction served two purposes. It would immediately provide access to additional copper deposits, and later could contribute to the grand plan to link Sydney and Darwin by inland rail and also be linked to partially built branch lines from Brisbane, Rockhampton and Townsville on Queensland's east coast. From 1911, some 100 kilometres of the line was surveyed from Malbon to Sulieman's Creek near Dajarra where it would connect to the proposed inland route.
In 1923 vast silver and lead deposits were discovered at Mount Isa 150 kilometres by road to the north of Dajarra. More business followed in 1929 when Duchess was connected by rail to Mount Isa. So far as Dajarra was concerned, a weekly mixed train plied the route from Cloncurry and Dajarra gradually became one of the world's largest railheads for cattle transported to eastern meatworks.
Supplies from Ballara quickly dwindled and the Trekelano spur lasted until 1943. Competing road transport eventually captured the cattle market and Dajarra railway station (21°41′47″S139°30′50″E / 21.6965°S 139.5139°E / -21.6965; 139.5139 (Dajarra railway station))[16] closed (the last train departed Dajarra in 1988) when the line from Duchess closed on 1 January 1994.[7] The grand plan of the inland rail link did not eventuate. However, in recent years a plan has been floated to link Queensland with the Northern Territory via Mount Isa and Camooweal in Queensland to the Adelaide-Darwin railway route in the Northern Territory.
