In the last few days I have been looking at the route of the Forest of Dean Tramway which was a major innovation in its day. Haie Hill Tunnel which was built for it in the very early 19th Century was for a short while the longest tunnel in the world. It was also one of the earliest tunnels built.

The tramway linked significant industrial concerns in the Forest of Dean with the Severn Estuary at Bullo Pill. The owners of the tramway were also behind the first serious attempt to tunnel under the Estuary.
