Are there any remaining level crossings of the swing boom type, in which the gate was swung across the road by an electric motor-driven rubber-tyred wheel? These were installed in quite large numbers by the North-Eastern Region of BR during the early-mid 1960s and last one that I can remember in use was at Cononley.....which were replaced by conventional lifting barriers as part of the Airedale resignalling in 1994. Other examples that I can remember back in the day were at Urlay Nook - between Dinsdale and Allen's West, Mason's Arms Crossing at Shildon, Blaydon, Morpeth and at least one of the Beverley crossings.
