Terratec Completes Factory Testing 4th New TBM for Mumbai Metro

Australia-based tunnel boring machine (TBM) manufacturer Terratec on this past Sunday completed factory acceptance tests (FAT) for the fourth of five new TBMs at their Guangzhou facility in China which will be used to build a section of Mumbai Metro’s 33.5 km Line-3 tunnels between Cuffe Parade and Aarey Colony.

Christened T59, this Ø6.68m dual-mode TBM will be deployed along with T58 by the Hindustan Construction Company – OSJC Moscow Metrostroy JV to exclusively build twin tunnel on the line’s 4.049 km package UGC-02 (Chhatrapati Shivaji Terminal Station – Mumbai Central TBM receiving shaft) which was awarded by the Mumbai Metro Rail Corporation Ltd. in July 2016.

As per the tunneling plan, T59 will be launched through the CST Station’s northern shaft and will be retrieved from Mumbai Central Station’s southern shaft after excavating 3556 meters for 4 tunnels on the down-line.

      703’s breakthrough was planned for today afternoon but didn’t take place. I’m trying to find out the exact reason.

      Everything was ready at AG-DMS – from banners to the TBM receiving cradle. Local ministers and top CMRL officials were present, but something went wrong and they had to cancel the event.
