The locks on the stretch of the Trent and Mersey canal between Kidsgrove and Wheelock were dualled to ease congestion in the 1830s after the success of the canal and the new Harecastle tunnel brought huge congestion. In my view the paired locks are among the finest canal architecture in the country, and it is a great disappointment that many of duplicates are now out of use - quite apart from the congestion caused where they single-down as at Thurlwood Upper, No. 53.

This is a poignant image as this is the first time I have visited this canal without a boat and my senior assistant has only ever had one canal trip. He's still looking for a boat to appear, though, because that's what they do when you wait at the bottom of a lock, ready to hop on.
