ABSTRACT:
A railway crossing structure for a railway track including an elastomeric gauge insert (50) fitting between each rail (10) and the adjacent gauge panel (12). Elastomeric gauge insert (50) has a body portion (70) formed by upper and outer sides (72, 74) separated by an elasticity cavity (76) and joined to each other at juncture (78) defining an outer sealing surface (80). Hinge lines formed by notches (82, 84) in sides (72, 74) assist in the folding or flexing of body portion (70) as shown in FIG. 6 during installation of gauge insert (50) by a pushing force exerted against upper surface (62) of body (52). Body portion (70) snaps beneath head (16) of rail (10) upon the seating of gauge insert (50) with leg (54) engaging arcuate connecting surface (36) of base (18) as shown in FIG. 3. Sealing surface (80) of body portion (70) seals against undersurface (30) along a relatively large sealing area and a relatively large sealing force is provided by compressed sides (72, 74).
