(54) Elastic tie plate for railway track


(57) Elastic tie plate for railway track, of a generally rectangular shape moulded with an ether-ester thermoplastic elastomer. On its upper face it has projections (1) arranged in rows and columns, positioned in the direction of the rail and with its upper face coplanar, said plane reaching as far as the plate edges (2) perpendicular to the rail, whilst the edges (3) parallel to it are situated in a slightly lower plane, forming rectangular bands (4) parallel to each side. On its lower face it has projections slightly smaller than projections (1), as well as discontinuous lips of truncated pyramid shape, on the sides perpendicular to the rail, which fit externally over the crosstie. The upper plane of the power face projections reaches as far as the four sides of the plate and extends on each of the sides parallel to the rail in corresponding flat lips (7), whilst on the perpendicular sides corresponding rectangular bands appear, on the inside and on an intermediate plane.
