The excavating and lining capacity of TBM christened Cora Coralina with100 m long, 11.66 m\u00a0 diameter and\u00a0 500 t weight is\u00a0 up to 15m daily. Involving engineers, mechanics, technicians and electricians, up to 150 people work directly on its operation, which takes place in three daily shifts and the TBM – equipped with back-up, hyperbaric chamber, ventilation system and segments erector – will excavate approximately 7.5 km of tunnel, part of the Line 2 extension.<\/p>\n
Extension of Line 2-Green <\/strong><\/p>\n In order to constructing a further 8.4 km section (8 km of which will be operational) with eight new stations, crossing the eastern zone of S\u00e3o Paulo, the Line 2-Green is being developed between Vila Prudente and Penha, while\u00a0 the S\u00e3o Paulo government’s budget is EUR 2.43 bn (BRL13.4 bn).
