Ellenbrook line

The Ellenbrook line, known as the Morley–Ellenbrook line during construction, is a suburban railway line in Perth, Western Australia, which is operated by the Public Transport Authority as part of the Transperth system. The line branches from the Midland line at Bayswater station and heads north-north-west to serve five stations along a 21.3-kilometre (13.2 mi) route to Ellenbrook. Ellenbrook line services continue west of Bayswater station alongside Midland and Airport line services to terminate at Perth station in the central business district.

Land for a transit line to Ellenbrook was reserved in the 1990s during the initial development of Ellenbrook. A railway line to Ellenbrook was promised by both major political parties in the leadup to the 2008 state election, but was cancelled by the newly-elected Liberal government after the election. After the Labor Party won the 2017 state election, planning for the Ellenbrook line restarted as part of the wider Metronet project. Enabling works within the Tonkin Highway median strip were undertaken by the Tonkin Gap project, which started construction in November 2020 and was completed in early 2024. The main Ellenbrook line contract was awarded to Laing O'Rourke in October 2020 and construction began in January 2022. The main contract's budget was A$1.123 billion, which increased to $1.651 billion in 2023. Track laying was completed by July 2024 and all stations were complete by November, allowing the Ellenbrook line to open on 8 December 2024.

Branching from the Midland line at Bayswater station, the Ellenbrook line enters the median strip of Tonkin Highway, the location of Morley and Noranda stations. After exiting the highway, the line runs along the southern and eastern edges of Whiteman Park, the location of Ballajura and Whiteman Park stations, before entering Ellenbrook to terminate at Ellenbrook station. The Ellenbrook line has a frequency of five trains per hour during peak and four trains per hour off peak, operated by B-series trains. The travel time from Ellenbrook to Perth is 31 minutes. All stations along the branch are fully accessible and have 150-metre-long (490 ft) platforms; train lengths are limited by 100-metre (330 ft) platforms between Perth and Bayswater. The branch was forecast to have 11,753 boardings per weekday upon opening, increasing to 18,070 boardings per weekday in 2031, but as of July 2025, the branch has 5,364 boardings per weekday.
