Electrification of the 440 km line built in the 1960s to tap iron ore deposits in the Bailadilla range was approved in 1970. Dropping 1000 m on a 1.7 per cent ruling gradient, regenerative braking offered substantial energy savings, while the projected annual traffic was five times the theoretical breakeven point where electrification becomes viable. Explains why work has been seriously delayed and some technical problems have still to be resolved. Overhead line currents may cause greater induced voltages in communication cables than was thought, power supplies are costly in this remote area, and regeneration has been abandoned for lack of suitable locomotives.
