Historic structures & features


The disused 180 m long Old Main Railway Tunnel (Redbank Range Tunnel) between Picton Junction and Thirlmere was opened in February 1867 and was the first railway tunnel to be used by the NSW Railways. It was closed to rail traffic in 1919 when the new deviation line opened. During World War II it was one of a number of disused railway tunnels in the Sydney area in which ammunition, mustard gas spray tanks and other military supplies were stored. After the RAAF moved out in 1950, it was used for commercial mushroom growing.
