in 1879 and the section of the line through to Aldgate was opened on 14 March 1883. This included service to the Belair railway station, located in Government Farm. In 1881, the South Australian government proposed subdividing the land of the farm to meet the increasing demand for land in the Adelaide Hills, but this was met with protests. This led to an Act of Parliament being passed in October 1883 prohibiting the sale of Government Farm without the sanction of Parliament. Further campaigns to protect the land during the 1880s, as well as the greater accessibility to the farm due to the construction of the Adelaide to Nairne Railway line, led to Government Farm being transformed into Belair National Park, proclaimed on 19 December 1891 with the passage of the National Park Act. Later development Belair was the location of the first facility for the treatment of alcoholism in South Australia, at the Belair Home for Inebriates. The retreat was partially funded by the government and opened in 1877. The building was renamed Hope Lodge in 1893 and operated as a training center for missionaries until 1907. Belair was also home to multiple sanatoriums for people suffering from tuberculosis. Kalyra Consumptive Home was incorporated in December 1894 by the James Brown Memorial Trust, with its first patients admitted in February or March 1895. Another sanatorium called Nunyara Tuberculosis Sanatorium was opened in 1902 by Dr Arthur Gault, which operated until his death in 1917. In 1915, quarries were opened at Sleep's Hill at the western end of Belair by Burt and Timms, who were contracted to build houses and roads in the nearby suburb of Colonel Light Gardens. Adelaide Quarries Ltd was formed in 1919 to better exploit the quarries, and by the 1950s the total production in the quarries had reached 7 million tonnes. In the 1920s, the Belair Progress Association was established to advocate for the development of Belair. They made efforts to stop blasting in nearby quarries and pushed the district council to repair Belair's roads. They also lobbied for Windy Point (then called Observation Point) to be set aside as a reserve, which led to the District Council of Mitcham acquiring the land in 1930. At this time, Belair was still a small country town with a population under 200. The population did not begin to grow until the late 1930s, when the population increased
