Tracks Under Conwy Castle, Picture 4, Edited Version, Conwy, Wales (UK), 2012

Here are the rail tunnels through the castle. These aren't unique in Britain, but are unusual, even surrealistic. This is the edited version, but I wasn't able to decide whether this one was better than the original. Consequently, I've posted both. The DMU was a Class 158 operated by Arriva, but I wasn't able to get the number.
