South Australian Railways Brill railcar
 The South Australian Railways Model 55 and 75 Brill railcars were two types of railcars that served the South Australian Railways for several decades (1925–1971). 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state's railway lines until they were eventually replaced by both the Bluebird and Redhen railcars with the last units withdrawn from SAR service in 1971.
