Fixed Crossing

This switchless crossing caught my eye and I stopped to get a shot of it.
"Fixed crossing
On a fixed railway crossing the open gap at a fixed V-crossing forms a weak point on the railway line where the heavily-loaded wheel must bump across the resulting gap of about 10 cm, supported only by the portion of the wheel tread which is on the wing rail. This pounds the rail so much that the steel can deform and/or wear away. This damage may easily spread to other components including the wheels, and the noise can be a nuisance. Scheduling repair of damage can also be a problem in high traffic locations." Wikipedia
