Terratec Completes Factory Testing 5th New TBM for Mumbai Metro
Australia-based tunnel boring machine (TBM) manufacturer Terratec yesterday completed factory acceptance tests (FAT) for the fifth and final new TBM at their Guangzhou facility in China which will be used to build a section of Mumbai Metro’s 33.5 km Line-3 tunnels.
Christened T62, this Ø6.68m dual-mode TBM will be deployed by the J Kumar Infraprojects – China Railway Tunnel Group JV along with 2 other (1st, 2nd) new dual-mode hard rock TBMs and 2 refurbished TBMs to build twin tunnels on the line’s 4.94 km package UGC-05 (Dharavi Station – CSIA T1 TBM receiving shaft) and 4.45 km package UGC-06 (CSIA T1 Station – CSIA T2 receiving shaft) which were awarded by the Mumbai Metro Rail Corporation Ltd. in July 2016.
As per the tunneling plan which might change, T62 will first be commissioned from CSIA T2 Station towards Sahar Road Station for building the 693m up-line tunnel and will then be dismantled, transported back & relaunched again on the same stretch for building the down-line tunnel.

All 5 contractors of the line plan to deploy a total of 17 TBMs to construct it, and with this development 14 TBMs have passed factory acceptance tests out of which 6 TBMs have been commissioned –
• Package UGC-01 – None
• Package UGC-02 – 2 Terratec TBMs (1st, 2nd) in China (new)
• Package UGC-03 – 1 Robbins TBM in Singapore (refurbished)
• Package UGC-04 – 3 Herrenknecht TBMs (1st, 2nd, 3rd) in China (new)
• Package UGC-05/06 – 2 Terratec TBMs in Delhi (refurbished) + 3 Terratec TBMs (1st, 2nd, 3rd – this post) in China (new)
• Package UGC-07 – 2 STEC TBMs in Singapore (refurbished) + 1 STEC TBM in China (new)
Terratec has now completed FAT for all 7 TBMs on order – 5 new and 2 refurbished machines. Robbins still has to complete FAT for 2 new Crossover XRE machines for use on package UGC-01 and 1 NFM Slurry machine for use on package UGC-03.

Sir I guess for package 3 Robbins machine have already reached in India from Singapore
Yes – the first machine (TBM 1238 / Tansa-1) arrived on February 12. Some images have been shared here – https://themetrorailguy.com/2018/02/21/mumbai-metro-line-3-february-2018-tunneling-update/
FAT is pending for one more machine on that package.
Thanks TMRG for the wonderful and timely updates. I have a feeling that Mumbai won’t pose a greater challenge in tunneling as did Bangalore and 3rd phase of Delhi Metro based on this old article.
