Coal was found on Black Jack Hill in 1877. By 1891, 6,000 tons of coal had been dug from shafts. The Gunnedah Colliery Company was registered in May, 1899. One month later a private railway some 5.7 km in length had been completed from the railway station to their mine. In September, 1957, the Government Railway took over the working of the line.
