This work investigates the final operational era of steam locomotives across the Australian rail network before their total displacement by diesel and electric power. Robert Wheatley documents this transition through a curated collection of visual evidence, capturing the mechanical decline and the cultural significance of steam transport. The text serves as a historical record of a specific technological epoch, utilizing photographic documentation to illustrate the operational realities of the period.

The subject matter points to a specialized historical reference intended for rail enthusiasts and historians interested in Australian industrial heritage. The framing suggests a visual-heavy, archival approach that prioritizes photographic evidence over technical narrative density.
