bridge. A passing loop is located before entering the tunnel, which climbs on a 12.5% gradient to the Perisher Valley terminal. A provision for a second 300-metre-long passing loop has been made inside the tunnel. To Blue Cow the line first drops downgrade, then climbs 1.3 kilometres on a 3% gradient, then climbs at 12.5% to the terminus. The railway reaches a maximum elevation of 1,905 metres above sea level at Mount Blue Cow station.

The depth of the tunnels varies from between , and their diameter between . second-hand rail from the State Rail Authority was used to build the line, and two electrical substations are fed with 33 kV power, and output 1.5 kV DC for the overhead wiring. Rolling stock To operate the service 11 carriages were built by Comeng, Granville and Fuji Heavy Industries. Each is long and wide, and can carry 225 passengers. This provides for the movement of around 4,500 people per hour. Eleven passenger cars in total were built, 4 motor cars, 4 driving trailers and 3 non driving trailers. The motor cars each have four traction motors, making them perhaps the most powerful rack railcars in the world. The braking system is mixed regenerative and rheostatic. The train is capable of , however this is limited during the downhill journey to . Two four-wheel 'S' open wagons were acquired from the State Rail Authority for freight traffic, and have been cut down to flat wagons. A 1958 Tulloch Limited built locomotive was also purchased.
