As operated by the WAGR, the line was from Boyanup to Flinders Bay. Only the first section of the line (Boyanup to RGC) remains in place, although disused, with few changes since it was last operated. The remainder of the line has been lifted, although the rail reserve as far as Busselton remains under the control of the
Public Transport Authority and is theoretically available for future rail uses. Like all railways outside of
Perth, the line was predominantly
single-track, with passing loops at various locations. The remnant section, from Boyanup to RGC, is controlled by
Arc Infrastructure. Within Busselton the line ran past the
jetty and along the foreshore, turning south through what is now the Busselton Health Campus. Heading west again along the route of what is now the Bussell Highway, the line served Vasse and Quindalup before turning south towards Flinders Bay. The line passed through forested and agricultural areas, including several municipally heritage-registered mill sites in the M.C. Davies timber concession area south of Margaret River.
Branches This line was the first branch from the Northcliffe line, at Boyanup, linking Busselton to the WAGR network.
Timber tramways Several timber mills used to operate along the railway, each with their own access to the mainline. Many of these mills operated extensive timber tramways that fed significant quantities of timber to the railway. The section from Witchcliffe to Flinders Bay was originally built as an M.C. Davies horse-drawn tramway, before being bought by the Government and upgraded to a WAGR line in 1925. ==Wadandi track==
