Having made our slow meandering way along the Trent and Mersey canal through Stoke we came to the 2926 yards long Harecastle tunnel, built to transport coal to the pottery kilns. This is the last of three that used to exist, built by Telford and now only allowing one way traffic at a time for safety. So, each end of the tunnel is looked after by a tunnel keeper to whom one introduces oneself upon arrival. The keeper gives clear instructions for safe use of the tunnel and what to do in an emergency.
We had to wait as three boats were coming through from the north end so to fill our time in a useful manner we filled up the water tank using the tap on the right side of the entrance.

As there are no air shafts in the tunnel, the entrance at the south end is closed and a fan is turned on to extract the fumes from the engine's exhausts after the boats have begun there voyage through the dark. There is a quarter circle hanging over the right hand side of the entrance held by the three chains you can see in the picture. If your boat and all that is on the roof can pass under this without touching it you will be able to pass safely through the tunnel.
