A railway level crossing (grade crossing) is described in which the road surface between the rails is, at least adjacent the rails, provided by flexible plates, e.g. rubber plates. The plates extend right to the rails and under their edge portions adjacent the rails are resilient support means which allow the plate to flex downwardly when engaged by the flange of a wheel passing on the rail. The resilient support may be a gas-filled tube extending parallel to the rail.

A railway level crossing comprising two spaced apart rails constituting the rail track at the crossing and a road surface between the rails substantially at the level of the top surfaces of the rails, wherein an unyielding bed is provided between the rails and, at least adjacent each of the rails, the said road surface between the rails being provided with at least one flexible plate which is supported by said unyielding bed and has an edge portion extending to closely adjacent the rail, said edge portion not being directly supported by said unyielding bed whereby said edge portion can bend downwardly when engaged by a flange of a flanged wheel passing along the rail, there further being provided resilient means supporting said edge portion of the flexible plate and adapted resiliently to restore said edge portion to its normal position when the flanged wheel has passed, said resilient means comprising at least one gas-filled sealed tube of flexible material extending beneath the said edge portion of the flexible plate parallel to the rail and supported by a base.
