Two models of the Brill railcar were operated by the South Australian Railways between 1925 and 1971. Introduced to run on country rail services, the "Barwell Bulls" serviced most of the state's railway lines until they were eventually replaced by both the Bluebird and Redhen railcars. The last units were withdrawn in 1971.
