CONSTRUCTION OF TARCOOLA - ALICE SPRINGS STANDARD GAUGE RAILWAY

This paper describes the construction of stage 2-Robin Rise to Marla Bore-of the Tarcoola-Alice Springs Railway, Western Australia. The railway consists of a single track of standard gauge railway 831 km long, capable of carrying 20 tonne axle loads. A feature of the line is the continuous welded rails and prestressed concrete sleepers. The new line is located approximately 150 km west of the existing narrow gauge link and is generally outside or near the Lake Eyre basin to avoid the many watercourses. Preliminary survey started in 1971 with construction commencing in April, 1975. Design standards applied to the new line are: ruling gradient 1 in 25; parabolic vertical curves inserted where net change of grade exceeds 0.2 per cent; minimum horizontal curve radius generally 1200 metres. A standard 60 M length cubic parabola transition is used for curves of all radii; bridges and structures designed by metric cooper M220 loading. All overhead structures provide a 4.25 M clear width to a height of 6 M above rail level and formation width is 7.5 to 9 M on embankments and 9 M minimum in cuttings. The overall budget cost for the project was $A145 M and the work was completed ahead of time and within budget.(a)
