In Los Angeles the Southland rail-transit system has created a massive tunnel-boring machine for a future subway station at Second and Hope streets as part of connector linking the Blue, Expo and Gold lines in downtown Los Angeles.
The machine began its work in October and the entire $1.75-billion project will be completed in 2021, the S-shaped tunnel will allow commuters to use a single train to move from Long Beach to Azusa and from East L.A. to Santa Monica, linking some of the county’s most far-flung residents without time-consuming transfers. Angeli journeyed 1,440 feet from Little Tokyo to Bunker Hill, crews have already set 18,000 tons of precast concrete in the machine’s wake and sealed the tube with 1,000 gallons of grout. The line is expected to serve 88,000 riders daily, including 17,000 new passengers, and cut travel times for some up to 20 minutes.

Galbiati Group builds TBM components such as planetary gearboxes, bearing supports, erectors. The company has recently realized one 4 ton-segment erector for a Tunnel Boring Machine designed for a excavation project. For more information visit the website www.galbiatigroup.it.
