: Metro Tunnels might utilise tunnel locos?

Some up-dates on possible construction railways (tunnel locomotives)

        Forrestfield-Airport Link - SI/NRW jv (C)


Disappointing news. These pictures from a few days ago show that the transport used for taking segment ring sets and grouting materials up to the TBM back-up, is being done by the dreaded pneumatic-tyred "multi purpose vehicle" (MPV) running directly on the raw ring surface. No conrail used.

         Sydney Metro, City & Southwest line - JH/CPB/Ghella jv (C)

The John Holland/CPB Contractors/Ghella jv have announced the TBM supplier for the Sydney Metro, City & Southwest line, Chatswood~Marrackville. The German manufacturer Herrenknecht will supply the four  DoubleShield TBMs and the fifth which will be a Hybrid MixedShield/Slurry TBM. These will be built in China. Still no firm indication as whether conrail or MPV to be used here (see previous sections to this post).
