Stay up to date with the progress of our tunnelling machines under the Thames. Rachel started tunnelling from Carnwath Road in Fulham (CRR), Millicent started tunnelling west from Kirtling Street in Battersea (KRS) while Ursula is tunnelling east from Kirtling Street. Charlotte is creating the 1.1km Frogmore Connection Tunnel from Dormay Street (DOS) in Wandsworth to Fulham. Two more TBMs will start working on the east section next year.
