Thornlie Line Extension

Post by Mr OC Benz »

This is the thread for discussion specific to the Thornlie rail extension. For general Metronet policy discussion, please use the existing thread.

A project overview document has been released on the PTA's Project webpage. Key elements are:
- 17.5km extension of Thornlie Line from Thornlie to Cockburn Central
- Two new stations at Nicholson Road and Ranford Road
- 3-kilometre duplication of track between Beckenham and Thornlie
- 14.5 kilometre extension to connect Thornlie and Cockburn Central stations
- Significant modifications to Thornlie Station to convert to through-station and accommodate six-car trains
- additional platform and significant track work at Cockburn Central to independently service the extension without impacting existing Mandurah Line services
- Will become an important transport interchange hub, reducing demand at Murdoch Station.
- Explore value capture opportunities in the area.

Expected journey times:
Nicholson Road to Perth: 25-27 mins | Nicholson Road to Cockburn Central: 9 mins
Ranford Road to Perth: 28-30 mins | Ranford Road to Cockburn Central: 6 mins

Predicted boardings at the two stations in 2021: 3,120
Predicted boardings at the two stations in 2031: 4,352

Potential for an additional two million service kilometres and up to 20 new buses in the area to support the extension. At this stage, almost all bus services which connect with Murdoch Station to be retained.

Project Definition Plan expected to be completed by early 2018. Four year period to opening. A new dedicated METRONET website will be available in late 2017.

In regards to the Thornlie to Cockburn rail extension, I was considering if this could coincide with the current "W" pattern services on the Mandurah line, which terminate at Cockburn, becoming "K" pattern services and extending to Rockingham. There is currently only one train per weekday operating to this pattern. This could save a lot of layover congestion at Cockburn and provide more frequent weekday rail services to the growing areas between Cockburn and Rockingham.

Layover congestion won’t be any worse than it is now at Cockburn given the Thornlie Line would be operated independently with its own track and platform and not rely on existing Mandurah Line tracks/platforms. Exception to this is special event trains from Mandurah which could run direct to Perth Stadium via Thornlie.

The key question for me is will the Thornlie Line service continue to run every 15 minutes in peak, or will it finally run every 10?

NEWest (CPB Contractors & Downer EDi) have officially won the contracts for the Thornlie-Cockburn Link & the Yanchep Rail Extension, announced at an event today to mark the start of construction on the Yanchep Rail Extension.
METRONET Website wrote:NEWest Alliance to build two METRONET projects
23 November 2019

The preferred alliance to construct both the Yanchep Rail Extension and Thornlie-Cockburn Link is NEWest Alliance.

The announcement was made at an event to mark the start of early works for the Yanchep Rail Extension.
Made up of CPB Contractors and Downer EDI, NEWest Alliance will work closely with the Public Transport Authority to progress the designs and construction schedule once the contract is signed next month.

Together the projects are set to create 3000 jobs and once operational will give residents of the northern and eastern suburbs greater access to employment and training, entertainment and recreation hubs.

The Yanchep Rail Extension will add 14.5km to the existing Joondalup Line, with stations at Alkimos, Eglinton and Yanchep. With early works already underway, construction will commence next year, and the first trains are expected to be running in 2022.

The Thornlie-Cockburn Link will close a 14.5km gap in the eastern rail corridor by linking communities between the Mandurah and Armadale lines. Stations will be built at Ranford Road and Nicholson Road in Canning Vale, and significant upgrades made to both Thornlie and Cockburn Central stations. Early works on the project will begin later this year.

For more information visit the Yanchep Rail Extension or Thornlie-Cockburn Link project pages.

Few artists impressions of Alkimos & Yanchep stations. Yanchep station has a 3 platform terminus

Got a source for it having three platforms other than the artist's impression? Have seen conflicting information on this, such as this fact sheet (admittedly, issued well over a year ago) which says there will only be two:

The Project Definition Plan states the ultimate design for Yanchep is for three platform faces to provide for operational efficiency and to handle expected patronage growth. There will definitely be two platform faces from day 1 but whether the third is also built at the same time remains to be seen. Not necessarily required from day 1.

There is also reference to a three platform face design for Alkimos but this is even less likely from day 1 but potentially necessary future proofing to accommodate a future East Wanneroo Line branching north of Clarkson.

Level crossing removal contracts awarded
Announcing the preferred proponents for two new contracts are important steps to removing up to seven level crossings on the Armadale line.

As early works start on the Denny Avenue Level Crossing Removal project, Downer EDI has been chosen as the preferred proponent to build the major rail components.

This is the first of two construction packages, with the road component contract set to be awarded in early 2020 for major works to begin next year. Downer EDI and Decmil are the two shortlisted proponents for this road package of works.

Planning to remove another six level crossings along the Armadale Line is also progressing with Jacobs named as the preferred proponent to develop the business case.

The expanded project scope for the business case includes the crossings at Oats Street, Mint Street and Welshpool Road in one package, and Wharf Street, Hamilton Street and William Street in another.

Appears though construction has started on the extension the inside lanes of the freeway have been closed from the Berrigan Drive bridge, looks like the 2 additional tracks will be laid the same time as the North Lake road bridge which is well advanced now too.

Apparently some of the freeway widening works around Cockburn were performed with the impending construction of the TCL in mind, although I haven't seen any plans for the work (or what is fast becoming the finished product) so not sure what aspects of the roadworks were going to accommodate the future platforms/tracks at Cockburn.

The intention is to tie the bridge structures for the Armadale North Lake road bridge and all of the infrastructure relating to the TCL extension by keeping one lane closed from Berrigan Drive in either direction so they don’t have to go back later the lane closure also allows work for rail widening under the bridge to take place and realignment of the crash barriers. Thornlie extension trains are meant to run independently from the Mandurah line on 2 separate tracks from the tunnel then back into a single track upon arrival at the dock platform so there will be 2 cockburn shuttles if that makes sense only footy and event trains will access the spur

The platform extension and realignment of rail crossovers can be managed by full and partial shutdowns of the inner Mandurah line
