Thornlie railway station is a temporarily closed railway station on the Transperth network. It was the terminus of the Thornlie line, a spur of the Armadale Line, seventeen kilometres (11 mi) from Perth Station serving the suburb of Thornlie, Western Australia. Under construction is the Thornlie-Cockburn Link which will link to Cockburn Central railway station along the Mandurah line via two new stations, Nicholson Road railway station and Ranford Road railway station.

History

In December 1999, legislation was tabled by the Government of Western Australia to build the Southern Suburbs Railway from a junction with the Armadale line east of Beckenham Station passing beneath Albany Highway, Roe Highway and the Kwinana freight line via the Kewdale Tunnel, then paralleling the freight line south to Jandakot before continuing via the median strip of the Kwinana Freeway.

However, in 2002, following a change in government, the Southern Suburbs Railway was altered to operate via a more direct route to Perth. By this stage the first part of the Kenwick Tunnel had been built.

To justify the completion of Kenwick Tunnel and other infrastructure, the route was converted into a short spur line to Thornlie.

The spur and Thornlie station opened on 7 August 2005.

Thornlie–Cockburn link

Thornlie station will be modified for the extension of the Thornlie line to Cockburn Central station on the Mandurah line. Modifications to occur include extending the two existing 100-metre (330 ft) long platforms to 150 metres (490 ft), to accommodate six car trains; construction of a concourse to link the two platforms, with lifts and stairs; modifications to the station's car park; changing the shared bike and pedestrian path, moving and replacing bicycle facilities; upgrading toilets, staff amenities, services and systems to modern standards; and replacing the nearby Western Power electricity substation. The station will remain in use during these works. The extension to Cockburn Central is planned to open in mid-2025.

Services
