Thanks to BB for his tours and hospitality
Opened in 1850 and closed to passenger traffic in 1960 followed by freight in 1990.
This is the first tunnel I have been in that has the lines and sleepers in situe. It has a very distinctive S bend (plus a smell of three week old curry!).
I was amazed by the bridges and the architecture (cuttings etc) around the Northern portal.
This tunnel is meant to be haunted
As per my usual routine we walked it and took pics on the return (pics from the Southern portal back to the North)
