Swingnose crossing

A swingnose crossing is a device used at a railway turnout to eliminate the gap at a V-crossing aka frog. Open crossings are a weak point on the railway line where the heavy wheel must jump a gap, pounding the rail so much that the steel can deform and/or wear away. The damage spreads to other components including the wheels, and the noise can also be a nusience. Repairing the damage can also be a problem if the railways are busy with trains, and few opportunities existing between trains to do the repairs.

The swingnose crossing also overcomes a limitation that gapped crossings can only be so fine an angle.

The swingnose crossing overcomes these limitations by closing the gap
