This tunnelling machine, was powered by a steam engine and was used to bore huge 80m circular tunnel and a failed 10m tunnel that both were drilled deep into the rock. However despite John Dickinson Bruntons efforts in him aiming to revolutionize quarrying. While yes he’d been very successful within these bored tunnels and had success in creating the quarried tunnels, yet the bore machine itself was far, far too difficult to even control and the whole operation was abandoned.
