    "First, reduce the tunnel diameter. The current standard for a one-lane tunnel is approximately 28 ft. By placing vehicles on a stabilised electric skate, the diameter can be reduced to less than 14 ft. Reducing the diameter in half reduces tunnelling costs by 3-4 times. Second, increase the speed of the Tunnel Boring Machine (TBM).
