Thornlie Line Extension

Postby Mr OC Benz » Mon Aug 21, 2017 2:45 pm

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?
