Rails Across Australia is an album of photographs taken by David Cable, a well-regarded British author of several albums of train pictures throughout the world.

The photos were taken initially during the period between 1967 and 1973 when David lived in Adelaide, and then during several visits around the Commonwealth during the twenty-first century.

The photos cover a wide variety of trains in the mainland states, from Queensland to the Pilbara region of Western Australia, and include pictures showing trains in the landscapes, as well as close-up photos of locomotives for the modelling enthusiasts.

The well-known problems of different gauges originally established in the various states are illustrated by the individual classes designed for them, in addition to the newest designs for the standard gauge tracks now linking them.
