For rural, low-traffic lines of the South Australian Railways, J.G. Brill developed the railcars of the models 55 and 75. They differed on the one hand by different lengths and on the other hand by petrol engines with an output of 68 and 186 hp, respectively. The 75 model was also combined with a trailer. They were used almost all over South Australia and were called “Barwell Bulls”. Later, all received more powerful diesel engines. They were replaced by Bluebird and Redhen railcars in rural areas in the 1950s and then used in the suburbs of Adelaide until 1971. ![](./images/status_hasBaseData.png)
