Skitube Alpine Railway
The Skitube Alpine Railway is an Australian standard gauge electric rack railway in the Kosciuszko National Park in New South Wales. It provides access to the snowfields at Blue Cow Mountain and the Perisher Valley.
==History==
In the 1980s development of the Thredbo and Perisher Valley skifields was increasing, but the mountain road providing access to them was limited, and road and carparking expansion works were financially and environmentally unacceptable. In 1980 the National Parks & Wildlife Service proposed the establishment of a day visitors resort at Blue Cow Mountain, which would increase the traffic demands. A number of transport modes were examined, including a funicular railway, chairlift, and an aerial gondola, but all were of limited capacity, affected by weather, and would scar the mountainsides.
A rack and pinion railway was found to be the best option, running mostly underground. The Perisher Skitube Joint Venture was established, with Transfield and Kumagai Gumi each holding a 49% share. The main proponent of the scheme, Canberra engineer Ken Bilston, held the remaining 2% share and was technical manager for the project.〔 Feasibility studies commenced in 1982 for a double track railway on the assumption that the road would close in winter, but this was altered to a single track line with passing loops when the closure was ruled out.
Construction commenced in October 1984, with tunnelling beginning in June 1985. The 3.3km Bilson Tunnel was constructed using a tunnel boring machine, while the 2.6km Blue Cow tunnel was constructed with the traditional "drill and blast" method. A consortium of Swiss and Australian companies provided the rolling stock, overhead wiring, sub-stations, communications and signalling. The line opened from Bullocks to Perisher on 26 July 1987 with the entire line opened through to Blue Cow on 31 March 1988.〔"Ski Tube Opening" ''Railway Digest'' September 1987 page 280〕〔"Skitube"''Railway Digest'' August 1988 pages 296-298〕
