摘要： An insulating rail boot encasing a rail embedded in concrete, asphalt or paver construction, including, shared right-of-way, dedicated right-of-way and at-grade crossing. The rail and the rail boot are secured in place by retaining clips. The rail boot has two exposed top surfaces and a plurality of longitudinal cavities within the body of the boot. The top surfaces of the rail boot are sloped away from the rail and are coextruded with a multi-durometer material that is more rigid and tougher that the elastomer of which the boot is primarily constructed. An outside edge of each top rail boot surface is positioned flush with a surface of the road material. This cooperation between the top surfaces of the rail boot and the road surface facilitates flow of water and debris away from the rail.
