By 1877, there was significant political pressure to minimise the diversion of trade from western New South Wales to Victoria and South Australia via river trade along the Darling and Murray rivers. The town of Bourke had become the key centre for pastoralists in western New South Wales since its formation in 1861. Provision was thus made to extend the line to Dubbo, reaching Wellington in 1880 and Dubbo in 1881. At the time, Dubbo had grown into a town of strategic importance on the stock routes between northern New South Wales and the Victorian goldfields. Beyond Dubbo, the railway opened up new land to European settlement, and was directly responsible for the development of townships. The line reached the future site of Narromine in 1883, and the railway station was the first building in the future settlement. The line reached the site of Nevertire in 1882, serving the nearby established village of Warren. Construction reached the site of Nyngan in 1883, with the nearby coach-stop village of Canonbar moving in its entirely to establish the town of Nyngan. Beyond Nyngan, the line swept across the plains in a straight line for, then the longest stretch of straight railway line in the world. It reached the temporary terminus of Byrock in 1884 before reaching its final destination of Bourke in 1885. The now-gone Station Master's residence was completed in the same year. A loading bank was built in 1890. A small coal stage, depot and drivers' barracks were added in 1891. In 1965, the station building was destroyed by a fire. It was replaced in 1968, becoming the first station building in New South Wales to be air-conditioned. The last freight train to Bourke ran 1989.
Services
Bourke was served by the Far West Express, which connected with the Western Mail from Sydney Central at Dubbo. The Far West Express was withdrawn by the Public Transport Commission on 20 September 1975 and was substituted by coaches. A NSW TrainLink coach service runs from Bourke to Dubbo. From Dubbo, the Central West Express operates to Central. In 2018, NSW TrainLink began trialling a day-return coach service from Bourke to Dubbo, as well as from Brewarrina to Dubbo. The service, running on Wednesday and Thursday, travels to Dubbo in the morning and returns in the evening.
Heritage listing
The 1968 station building at Bourke is notable as the first railway station building in NSW to be air conditioned. The site is also significant as one of the more remote railway precincts in NSW. The Bourke Railway Precinct was listed on the NSW State agency heritage register via s.170 of the Heritage Act, having satisfied the following criteria. The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in NSW. The station building has some technical significance as the first railway station to be air conditioned in NSW.
