Claim:
A rail mount comprising: a generally rectangular top plate formed with a central rail receiving surface on a top of said top plate flanked at opposite ends of said receiving surface by eyes adapted to receive e-clips for securing a rail to the rail mount on said receiving surface, said top plate having a planar bottom surface, said receiving surface being canted with respect to a plane of said bottom surface, said top plate having upwardly extending ribs over a full width of the top plate at opposite ends thereof, each rib having an outer flank perpendicular to said plane, an inner flank inclined at an angle of substantially 30° to 60° to a vertical, and a rounded junction between said flanks; a frame having a rectangular opening receiving said top plate with all-around clearance, said frame having a bottom surface spaced below said bottom surface of said plate and defining a cavity underlying said plate and communicating with said all-around clearance, said frame being further formed with hoods at opposite ends thereof reaching inwardly over said ribs and spaced above said ribs, and with four outwardly extending lugs located respectively along opposite longitudinal sides of said frame at each end thereof, said lugs being formed with openings enabling the passage of anchor bolts for securing the rail mount to a support; and a body of elastomer bonded to both said top plate and said frame at all surfaces of said top plate and said frame contacted by said body of elastomer, said body of elastomer filling said cavity and said clearance and having a bottom formed with spaced apart pads of said elastomer and bearing load against said support varying as a train rides over said rail, said elastomer filling gaps between said hoods and said ribs and extending downwardly along said inner flanks.
