More pictures taken during the unearthing of the main adit

and the subsequent work done on cleaning it up and making the area safe for viewing

This is the view looking down from above the adit.  Railway tracks have been uncovered and are found to lead directly into the adit.
This picture shows the unearthed top concrete lip and the first letter found  "M"
When the concrete sign was cleared, a bit of delicate 'hands on' work was needed to push through a hole and see what was inside.

 

Torch, excavator and digital camera were all there  -  just in case.

Everyone lined up to get a photo with the sign.
