SURAT (Metro Rail News): Terratec performed factory acceptance tests (FAT) on the only new tunnel boring machine (TBM) for Surat Metro’s Phase 1 project’s 7.02 km underground stretch connecting Chowk Bazar and Kapodra in January.
Gulermak – Sam India Builtwell JV will use this 6.61m earth pressure balance (EPB) TBM, S94, along with TBM S78 from Pune Metro, to build twin tunnels between Kapodra Ramp (North Ramp) and Surat Railway Station on the 21.61 km Line-1 (Sarthana – Dream City).
