INTERFACE STRIP FOR ROAD/RAIL CROSSING |
摘要 |
At a road/rail crossing, rubber inserts are located alongside the rails, between the rail and the asphalt of the road. The insert has a resilient nose, which engages the under-face of the head of the rail. The insert does not touch the web of the rail, but rath er the insert is wedged between the head and the flange of the rail. This engagemen t assists in locking the insert to the rail, by self-locking-taper action.
