Glenfinnan Viaduct

The Jacobite steam train crossing the curving Glenfinnan Viaduct in the Scottish Highlands, in autumn colors. Its 21 concrete arches carry the Hogwarts Express through the Harry Potter films, and in Chamber of Secrets (2002) Harry and Ron's flying Ford Anglia swoops in and out of them with the train bearing down. The Jacobite still makes the run between Fort William and Mallaig through the summer season, so you can either ride it or join the crowd on the hillside path above the viaduct to watch it steam past.
