"When Robert Stephenson's new railway tunnel to Lime Street Station was being dug in the 1830s, the navvies were hacking away deep underground and suddenly a hole opened beneath them. Staring up at them through the hole were Williamson's workers, busy digging their own tunnel underneath. The rail workers ran for their lives, fearing they had broken through to the devil's kingdom. Once the situation was explained, Williamson and Stephenson met and inspected each others' works. Stephenson was most impressed by Williamson's tunnels."

Well done Fuse!
If you ever come to Liverpool you can now visit them
New Visitor centre is opening shortly.
There was a documentary on TV recently and it showed where Williamson tunnelled(still finding tunnels) It was a giant pre Victorian Job creation scheme (ironically they are using a job creation scheme to excavate it. Future history books will not mention that)
