Forrestfield is a suburb of the City of Kalamunda in Western Australia. It lies 15 kilometres to the south-east of Perth at the base of the Darling Scarp and the southern border of Perth Airport. The suburb is split by Roe Highway into a southern residential area and a northern industrial area. The suburb is adjacent to Wattle Grove, Cloverdale and Kalamunda. Industrial area Rail The industrial area contains a major rail hub. The 241 hectare Forrestfield Marshalling Yard was built adjacent to the Kwinana railway line opening in stages between 1968 and 1973 in conjunction with the nearby Kewdale Freight Terminal as a replacement for the Perth marshalling yard and two other inner Perth yards. Within the confines of the yard, separate depots were built for locomotive, carriage and wagon maintenance. It was previously used by the Western Australian Government Railways, Westrail and Australian Railroad Group. As at January 2018, Aurizon, SCT Logistics and Watco Australia use the yard. Aurizon closed its terminal in late-2017 as part of the closure of its intermodal business. Gemco Rail also has a facility. Bounded by Dundas Road to the east, the Tonkin Highway to the south and Perth Airport to the west, some of the land was no longer required for railway by in the late 1990s and rezoned for industrial use. A combined 102 hectares was sold to the CBH Group, LandCorp and Specialised Container Transport. CBH Group's Metro Grains Centre was completed in 1998. In mid-2005 BlueScope constructed a large warehouse on former Westrail land. Kenworth DAF Trucks also relocated from Guildford to a new complex on Abernethy Road in 2005. Infrastructure In November 2016, construction commenced on the Airport line that is scheduled to open in 2021. Included will be High Wycombe station. The Western Australian Government has prompted the City of Kalamunda to investigate the possibility of business and infrastructure opportunities arising from the completion of the new link for Forrestfield and its surrounding areas. The completion of the Airport Link is expected to facilitate the continuing growth of Perth Airport as a nationally integral part of employment, commerce and international trade. Forrestfield's northern and eastern outskirts are home to the majority of the areas industrial enterprise. The area is host to a wide range of commercial business-to-business industries. Some of the most notable occupants include Grace Removals, Improvid and the Super Retail Group. History Settlement of the
