Rhyndaston Tunnel

The Rhyndaston Tunnel is a 955-metre-long (3,133 ft), 1-in-40-grade (2.5%) railway tunnel in southern Tasmania. The northern end of the tunnel is 72.5 kilometres (45.0 mi) from the Hobart railway yards. It was built as part of the Tasmanian Main Line Company's track from Hobart to Western Junction which was completed in 1876.[1]

International containers

The original tunnel was too small to take the original 2.4-by-2.4-metre (8 by 8 ft) international containers. The tunnel was widened in the early 1970s using a tunnel boring machine mounted on railway wheels, which was maneuvered into place between trains to excavate a few metres at a time.

The later and larger containers may again be too big.

Due to poor ventilation, diesel trains occasionally lose oxygen and fail to make it up the tunnel.

The tunnel is located 422 metres (1,385 ft) AHD .
