The first line in Sussex this one. It was built to move stone from the quarries behind the Chalk Pit Inn in Offham, down to the river to be moved away by barge. The spectacularly engineered tunnels under the road are impressive (and very difficult to get to without risking injury, don’t try it, just watch it here), but the brick remains of the base station also make interesting viewing too. Includes constant running commentary.
Newly added in 2007 is some panoramic footage from the top of the quarry, showing the start of the line and the wide sweep of the Ouse flood plain below.
