In the 1990's we went on a PDMHS bus trip to the Black Country Museum, which included a boat trip into the limestone caverns that include the "Singing Cavern" which is accessed off the Dudley canal tunnel. This was an interesting trip and is ideal for a family contemplating a day out.
However, back in 1963/64 when the Tipton portal of the Dudley Canal Tunnel was in danger of being blocked by railway plans to block the portal by building an embankment because of the railway line crossing directly above the portal, Dudley Canal Tunnel Preservation Society was formed to opposite this work, PDMHS members supported the fight to save the tunnel entrance. Most people thought that the entrance would be lost and a trip was arranged on which Trevor Ford booked places for a few lucky PDMHS members to to be legged through the tunnel. Members from all over the country (Sheffield, Leicester, Southampton etc.) congregated early morning at the Tipton portal joining up with many other people from different societies, all of us with the same intention to stop the portal being blocked. We jumped into a steel barge that had carried coal still with the coal dust in it, no seats, we all stood tightly packed together, most of us wearing our caving helmets and carbide lamps and away we went. After passing through the Castle Hill basin we entered the tunnel and volunteers took it in turn to leg the tunnel (it is 3172 yards long) through to Park Head where we had a picnic prior to the return trip. It's not boring, especially if one likes being underground and it certainly opened my eyes to the hard life of a bargee and his family. I had a 2 x gt. grandfather who was a bargee on the Derby/Coventry canals with his family, delivering coal in the early/mid 1800's before the arrival of the railway. My gt. grandmother Ann Cotton was born whilst her parents were working the Coventry canal.
For anyone interested in reading about the Dudley limestone mines, PDMHS and Shropshire Mining & Caving club published a joint publication (P.D.M.H.S. Bulletin, Volumne 14, No. 1, Summer 1999; Shropshire Mining & Caving Club Account No. 23), the author was Steve Powell.
