It’s been a while since we took a look at the City Rail Link and they’ve been putting out some pretty interesting images, videos and information on their social media channels recently so here are some of the best ones.
Yesterday CRL released this video of a drone flying through the Te Waihorotiu station. One thing that is notable is that the civil works on the project will be completed by Easter and the majority of the work has shifted to fitting out the stations and tunnels. That work is expected to take till Easter 2024 when the project moves into a “testing and commissioning” phase.
They also recently released this image looking at the station from the platform that in a few years, should be bustling with people.
They say the tracks between Britomart and Te Waihorotiu are nearly complete. You can also see some of the traction systems starting to go in too.
And then there’s this from Karanga-a-Hape where the platform is also being installed.
That’s a big improvement from a month or so ago when there was flooding inside the tunnels. Thankfully there was no significant damage from the flooding at any of the CRL sites.
There’s been a little bit of noise about this recently but I understand that Auckland Transport will soon be consulting on some proposed street changes around the Karanga-a-Hape station. Ideally this would mean changes such as closing off Mercury Lane to vehicles – there doesn’t seem need for it as nothing that can’t be accessed other ways, and improving Pitt St.
Further south at Maungawhau, tracks and other systems are starting to be installed in the bored tunnels
The last of the concrete has also been poured for the track base where the line into the tunnel splits off from the Western Line. In the image below you can also see the start new platform that will serve trains heading into the tunnel.
The westbound track through the Maungawhau site along with the traction equipment appears to be almost complete but CRL say it won’t be in use for double-track operation till the mid-year. With the recent appearance of sleepers and tracks to the site, I imagine it shouldn’t be too long till we see them start to head into the tunnel.
The footage here is from December so a bit old now but its good for putting into perspective the size of the site and where things are at.
Yesterday CRL gave some numbers on just what is involved in the fit out, and they’re substantial.
The fit-out, including architectural elements, includes installing the tracks, sleepers, electronics, safety systems and other essential componentry. The logistics involved are boggling:
- more than 16kms of rail track
- 816kms of signal cables
- 247kms low voltage cables
- 86km traction cables
- 74kms cable containment
- over 5,100m2 metal cladding and
- Around 4,000m2 of glazing.
CRL delivery partner Link Alliance has established a Systems Integration Facility (SIF) at the old Chief Post Office in Britomart, reopened to public acclaim, to integrate the CRL software and hardware into existing KiwiRail and Auckland Transport systems.
This programme of work is difficult and critical to the success of the CRL when it opens. It’s taken seven months to acquire all the software and hardware (COVID-19 disrupted the supply chain), with two kilometres of cable just to connect the SIF and before it is even integrated into the system.
Finally, the one major unknown with the CRL that we’re still waiting to hear about is what it will now cost and when it will be finished. In a select committee hearing a few weeks ago, CRL said this was likely to be within 10-12 weeks.
