The first passenger carriages of the Victorian Railways (VR) were fixed-wheel, with a mixture of first- and second-class bodies on either four- or six-wheeled underframes. They were built to the British side-loading, swing-door, cross bench compartment (non-corridor) style; later a saloon style was used to a limited extent, featuring fewer doors per side and perimeter seating - which increased total capacity by allowing more standing passengers.

As the Victorian Railways' fleet of Z vans began to age, the railways decided to invest in bogie designs for vans. Some van designs were included in a class of new passenger vehicles. Many other vans, for both freight and passenger work, were built separately from any other rolling stock developments, and these are the ones that feature here in detail.
