Peterborough: How Did Three Rail Gauges Shape a Town?

Peterborough lies in South Australia's Mid North, on Ngadjuri Country, about 220 kilometres from Adelaide. Originally named Petersburg, the town developed with agricultural settlement and the railway in the late nineteenth century; anti-German sentiment during the First World War later prompted its renaming. What made it distinctive was not simply that trains passed through, but that different railway systems and track gauges met there.

Australia's colonies built their early railways separately and did not adopt one gauge. Peterborough eventually connected narrow-, standard- and broad-gauge lines. Wagons could not simply roll from one gauge to another, so freight, passengers and rolling stock had to be transferred. Locomotives also needed inspection, maintenance, marshalling and scheduling. The railway was therefore not merely a line outside town but a system that continually created jobs, skills and daily routines. The depot, roundhouse, workshops and railway housing brought transport work into community life, while grain from surrounding farms moved through the junction towards ports.

Steamtown Heritage Rail Centre now preserves locomotives, original workshops and the heritage-listed roundhouse. Its operating triple-gauge turntable best explains the town's history. Three sets of rails share one machine, allowing rolling stock of different gauges to be turned and directed into the appropriate bays. It may look like an engineering curiosity, but it records the large amount of local labour produced by Australia's long-standing railway incompatibilities.

Peterborough shows that a regional town can be formed not only by a resource, but by an interface between systems that do not fit together. Gauge differences raised transport costs while concentrating transfer work, maintenance and knowledge in one place. When railway activity declined, many jobs disappeared. The surviving turntable matters not merely because it still moves, but because it reveals how one town once managed difference for a much larger transport network.
