several bridges is on the State Register of Heritage Places and considered the most scenic part of the line. Bridges The line crosses a few notable bridges, with the curved , Warren River Bridge being listed on the State Register of Heritage Places. Other notable bridges include: Preston River Bridge at Boyanup Balingup Brook Bridge at Balingup Blackwood River Bridge at Bridgetown Dombakup Bridge near Dombakup In particular, the section from Pemberton to Northcliffe features seven bridges, six of which are within south of Pemberton. Of those, three are within a stretch of the line. The final bridge, over Dombakup Brook is a completely wooden trestle bridge, of which no examples are known to be still in use. Branches While the Bunbury-Picton section of the South Western Railway was part of the original line to Boyanup, it is now considered part of the mainline, with the Northcliffe Branch connecting to it at Picton. The first junction en route is at Boyanup, where the Flinders Bay Branch diverges to the west, providing access to the Nannup Branch at Wonnerup. Further south at Donnybrook, the Donnybrook-Katanning Branch provided a connection to the east. 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 Jardee to Pemberton was originally built as a State Saw Mills tramway, before being transferred to the WAGR 12 years later, in 1926. Operations Passenger The only passenger services on the line are operated by the Pemberton Tramway Company. This tourist service is currently limited to the section between Pemberton and The Cascades, operated by diesel trams. Previously, the company operated passenger services along its entire section of the line, with steam-hauled trains Pemberton-Lyall and diesel trams Pemberton-Northcliffe. Stations With the line largely disused and the only passenger services operating from Pemberton, most railway stations have disappeared. However, several towns have preserved their stations, potentially re-purposing them for other uses: Donnybrook Greenbushes Bridgetown Manjimup Pemberton Freight There are currently no freight services on the line, with only the first in use as part of Picton Yard. However, it has been proposed that the line be rehabilitated and reopened between Picton and Greenbushes to carry lithium ore from the Talison Lithium mine near the town. It is hoped that the reopened
