 Most of the mills and tramways were built by the Colonial Sugar Refining Company (CSR), an Australian-owned company, and were transferred to the Fiji Sugar Corporation in 1973, when CSR withdrew from Fiji.Many lines were on road reserve provided by the government; combined road-rail bridges were common.Some passenger services were provided, such as the famous Free Train from 1915, with one or two trains a week from Lautoka to Kavanagasau and Rarawai on the Rarawai–Kavanagasau Light Railway.
