The Kwinana freight railway lines are a network of railways predominantly servicing the heavy industrial areas at Kwinana Beach south of Perth and to provide for the transport of freight servicing Fremantle Harbour, Kewdale Intermodal Facility and other freight destinations Perth. While some lines were constructed in the 1900s, most of the network was constructed in the 1950s and 1960s. Arc Infrastructure leases the majority of the network, with the exception of privately owned spur lines. Route Components The Kwinana and Forrestfield freight rail network comprises several sections of lines including sections which have now been closed, existing and proposed, which are described below. Robbs Jetty–Kwinana After 1898 the Fremantle railway line terminated at Robbs Jetty in North Coogee. On 1 July 1903 the line was extended south along the coast to Coogee servicing Woodman Point.: On 19 December 1955 the line was extended to Kwinana to provide a rail service to the Kwinana Oil Refinery The line was made redundant by the later construction of the freight line further east, and on 16 September 1973 the section between Coogee and Naval Base (north of the Alcoa refinery) was closed. The section between Robbs Jetty and Coogee closed in February 1986. Robbs Jetty–Armadale A line between Robbs Jetty and Jandakot (including Spearwood) was opened in 1906, and the line was extended to Armadale in 1907 as a means of providing transport for agricultural goods in the Forrestdale area to Fremantle Harbour. With the construction of a new railway line between Kewdale and Cockburn, the Jandakot to Armadale section closed on 23 January 1964, followed by Bibra Lake to Jandakot on 6 June 1966. The Spearwood to Bibra Lake section was retained to serve CBH Group and Elders Limited sidings until it too closed in 1991. The section between Robbs Jetty and Spearwood remains in use today. Spearwood–Cockburn Cement A branch line was constructed off the Robbs Jetty–Armadale line at Spearwood to link with the Cockburn Cement plant in Munster in 1961. The line now forms part of the main freight line between Kwinana and Fremantle. Midland Junction–Kewdale–Welshpool A freight railway was constructed between the Midland railway line west of the Midland Junction railway station and the Armadale railway line at Welshpool in 1957. The line provided access to the Kewdale Intermodal Facility - a major (if not the main) rail freight terminal in Perth. The section between Kewdale and Welshpool
