An insert for use in a level railway crossing includes an elongated high molecular weight body defined by a generally trapezoidal head with one planar vertical side edge, a shoulder extending outwardly and downwardly from the other side edge of the head for bearing against the bottom of one side of the head of a rail, a bottom portion for extending downwardly into engagement with the top surface of the base of the rail at the junction between such top surface and the vertical web of the rail, and circular cross section seals in longitudinally extending rectangular grooves in the one side edge of the head and in the inclined top surface of the shoulder for sealing with an adjacent plank and with the rail. The insert restricts the entry of the water and other foreign matter into the area of the bottom of the rails.

A railway crossing structure for use in a railway crossing of the type defined by center planks between the rails and outside planks on the outer sides of the rails and the rails being retained in place by rail clips, said structure comprising: (a) first elongated body means for insertion between a plank and one side of a rail, (b) second elongated body means for insertion between another plank and the other side of the rail, (c) each of said body means including a head portion having one straight side edge for engaging one side edge of a plank and a shoulder extending outwardly from the other side edge of said head portion for insertion beneath the head of a rail, (d) said head portion of said first elongated body means extending from a top edge of the rail to a top edge of the plank when inserted between the rail and the side edge of the plank, (e) said head portion of said second elongated body means having a portion for providing a recess below the top edge of the rail when inserted between the rail and the side edge of the other plank, (f) both first and second elongated body means having an inclined bottom portion extending downwardly from said head portion to a foot portion for resting on an inner top edge of a bottom flange of the rail; and, (g) whereby, said head portions provide a cover over the rail clips and provide an open space around the rail clips permitting the rail clips to flex when said first and second elongated body means are inserted.
