Описание к видео HS2 Construction Update - Bromford Tunnel near Water Orton Birmingham

Bromford Tunnel is a 3.5 mile (5.6km) twin-bore high-speed rail tunnel. Two huge tunnel boring machines (TBMs) are being used to dig it between Water Orton in North Warwickshire and Washwood Heath in Birmingham.

TBM Mary Ann is digging the first bore and was launched in August 2023. TBM Elizabeth is digging the second bore and was launched in March 2024. The tunnelling operation is being delivered by around 450 people working around the clock. Each bore will take around 16 months and 1.87 million tonnes of material will be excavated and sifted at the on-site slurry treatment plant to be reused on nearby sites at the Delta Junction.
