A top plate (5) for an elastomeric rail fastening assembly has a downwardly tapering lower wall (22) terminating in an inwardly-directed lip (25) defining a mouth (26) leading into a well (24). The cavity of the well (24) extends upwardly to provide the interiors of rail-holding mounts (10) between which a bottom flange of a rail may be located. The mounts (10) have open-ended sockets (11) for receiving spring clips used to hold the rail in position between the mounts (10), and the sockets (11) and well (24) communicate with one another. This form of top plate allows less metal to be used for its construction, requires less dressing after casting, and, precisely locates the sockets with respect to one another.
L'invention porte sur une semelle sous rail (5) pour ensemble élastique de fixation de voie dont les parois latérales inférieures (22) inclinées vers l'intérieur se terminent par une lèvre (25) tournée vers l'intérieur et délimitant un orifice se prolongeant par une cavité (24). Ladite cavité (24) présente deux protubérances dirigées vers le haut et entre lesquelles se place le patin du rail. Lesdites protubérances (10) présentent des passages (11) recevant les crapauds élastiques maintenant le rail entre elles, lesdits passages (11) communiquant avec la cavité (24). Cette forme de semelle sous rail nécessite moins de métal pour sa fabrication, moins de rectifications après moulage, et permet une localision plus précise des boulons de fixation des attaches l'un par rapport à l'autre.
