The Lochiel railway line was a railway line that branched off the Adelaide-Port Augusta railway line at Bumbunga. It opened in 1926 and closed in 1981.
The Lochiel railway line opened in 1926 being 5 miles in length. It was built to serve the Australian Salt Company salt works which had been operating since the late 1880s on Lake Bumbunga. Along a station, a siding was laid to the company's refinery on the shore of the lake, about three-quarters of a mile away. There was also a siding at Bumbunga. The line closed in 1981 when the salt works were closed and salt harvesting became a stop-start business managed from afar.
