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.

The class S double-decker multiple units played an important role in local transport in the Sydney area between 1972 and 2019. They were recognizable by their corrugated iron side walls and were the last Sydney Trains vehicles that were not air-conditioned. Comeng and A Goninan & Co. built 287 motor cars, 67 trailers and 85 control cars. The trains were initially used as four-car “S-sets” or two-car “T-sets”. Later, the trains were put together into other combinations and all control cars were converted into trailers. From 2012 they were replaced by the new class A and B.

The class A and B double-decker multiple units are the most modern vehicles in Sydney's commuter transport system. The nickname “Waratah” stands for the heraldic flower of New South Wales. They are based on class M and were developed with the help of Hitachi. Production of the car bodies is partly carried out in China by CNR and continues in Australia by Downer.

While the older Sydney Trains sets consisted of four cars each and two sets were usually coupled together, each train now consists of eight cars. Four of them are powered on all four axles. After 78 A sets, 24 B sets were built, which have modernized interiors and electronics.

The “Regional Fast Rail” project was launched in Victoria in 2000 to significantly speed up passenger transport in rural areas and make it more attractive. The aim was to increase the line speed to 160 km/h on at least some of the lines. To this end, some routes were upgraded, including fully gated level crossings and the TPWS train control system. The order to develop the appropriate multiple units went to the German Adtranz, which operated a plant in the Melbourne suburb of Dandenong.

Adtranz, which was taken over by Bombardier a short time later, initially developed the trains known as “VLocity” as two-car units. Since the car bodies of the Endeavor trains, also built in Dandenong, were not suitable for the required 160 km/h, the more streamlined design of the Transperth B series was used. As with the Voyager diesel multiple units built by Bombardier in Europe at the same time, a Cummins QSK19 engine with 750 hp was used in each car. However, the power was not transmitted electrically, but hydraulically.

The construction of the first 29 two-car multiple units began in 2004. Due to the good reception of the new, faster connections, repeat orders were constantly being placed. Since the trains only had four instead of five seats per row compared to the earlier V/Line railcars, additional intermediate cars with an additional engine were ordered. Later more trains were built from the factory with three cars. Internally, these were given the type designations 3VL and 3VR and differed only in terms of the interior equipment. Other vehicles for use on standard-gauge routes were listed as 3VS. Production is still ongoing today, so that by May 2022 a total of 94 three-car units had been completed and 24 more had been ordered.
