Bayswater Junction

Construction update

During two 56-hour shutdowns in February and March 2021 the final shift of the Midland Line tracks was completed, and the new section of the alignment commissioned. These tracks are now located in their permanent locations just south of their original location, following temporary relocation in December 2017 to make room for the construction of the Bayswater Junction dive structure.

A further 76-hour shutdown took place on 11 February to 14 February to tie in rail systems (e.g. signalling, communications). A 800m-long section of the overhead line equipment at Bayswater Junction is now live and officially part of the rail network.  

The western end of the principal shared path (PSP) has been handed over to the New Bayswater Station project. Works have begun to build a retaining wall as part of the track alignment for the new station. The new PSP along Whatley Crescent will need to remain closed while these works take place.

At the eastern end of the site, the 25kV Track Sectioning Cabin has been connected to the overhead power supply infrastructure within the dive structure. Located next to the Bayswater tunnel portal building, automated switches within the cabin control the 'neutral zone', a non-electrified section between the Airport and Midland lines.

Works are also wrapping up in and around the portal building, with earthworks and drainage installation underway on the outside and commissioning activities in the lead up to the final energisation ongoing on the inside.

Demobilisation works are now underway, with equipment and materials being removed from site and concrete slabs broken up where plant and offices once stood.

Bayswater Junction

Bayswater Junction refers to the area of rail reserve between Railway Parade and Whatley Crescent (from Cobden Street to Guildford Road) where the Airport Line spurs off the Midland Line and trains will enter/exit the twin-bored tunnels.

Bayswater Junction includes:

  • dive structure (an underground, open-air structure which leads towards the tunnel portal),
  • rail overpass (located above the dive structure, where trains travelling on the Midland Line will cross the Airport Line),
  • tunnel portal (underground structure where trains travelling on the Airport Line will enter/exit the tunnels), and
  • supporting infrastructure (tunnel portal building).

Bayswater Station

The new Bayswater Station will become a major transport hub with the Airport and Morley-Ellenbrook lines connecting to the Midland Line here.

To reflect its importance as an interchange station and heart of the Bayswater town centre, the station is undergoing a major upgrade, including additional rail infrastructure between Bayswater and Meltham stations to allow trains to turn around.

The METRONET team and the City of Bayswater are working together to create a precinct and station upgrade that provides the best outcomes for the network and local community.
