New to the site and happy to be here.

I found the TBM tracking page online here https://crossriverrail.qld.gov.au/construction/guide-to-tunnelling/tbm-tracker/ and was expecting to have a map of where the machines are currently located and I was not disappointed.  I found the details of how far they have both traveled and where they are exactly.

Is the same available for the Melbourne Metro Tunnel Project?

Thank you very much for the link you provided and I note Joan is almost complete in her work.  On the map at least the cross river network does look a lot longer than what is the Melbourne network.

I have wondered what will happen to all the TBMs crossriver rail and Melbourne when their job is completed?

It might look longer but it uses the existing Exhibition line between Roma Street and Bowen Hills.

TBM's frequently have a single job working career either digging their own grave at the end or being cut up for scrap.

I could be mistaken but I thought the TBM's that were used in the Sydney NWRL were not used for the Metro extension to the City despite the project following immediately after for the same line.

I don't think you are mistaken. Remember the tunnels for the Metro are smaller than those of the ECRL.

I read at one point that the Melbourne TBMs will be extracted once they’ve arrived at Town Hall.
No idea if that’s still the plan but they’ve definitely been extracted and turned at least once each.

Thanks, I was actually referring to the Chatswood to Sydenham Metro project.

It would appear a mix of recycling the TBM's in both parts and as melted down.

Here is one from the US, all melted down

Found this regarding Sydney
https://www.geplus.co.uk/news/sydney-metro-tbm-dismantling-gets-underway-27-02-2020/

Four tunnel boring machines (TBMs) used to drive the tunnels for the new Sydney Metro are starting to be dismantled following completion of the drives for the project.
The 100t cutter heads are the first sections to be lifted out and will be returned to the manufacturer.
The TBMs – named Mum Shirl, Nancy, Wendy and Mabel – drove a total of 30km of tunnels on the metro scheme.
