A rail tie plate (410,420,440,460,478) comprises two elements each provided with a rail flange shoulder (414), a downward leg (421) and a lateral projection (422) whereby the tie plate can be installed on a plate member (21, 121, 221, 321) of a slotted steel tie (20, 120, 220, 320) by insertion of the projection (422) of each element into a respective slot and rotation of the element inwardly and downward. A tie plate (410, 420, 440, 450, 460, 478) having longitudinal shoulders (414) is provided with a downwardly facing abutment surface such as provided by an opening (424) laterally through each shoulder (414) on which a rail clip (430, 470, 482, 489) engages to bear on an upper side of the rail flange (416). Rail rollover is avoided by transferring rotational forces to the plate (410, 420, 440, 450, 460, 478) through the engagement of the clip (430, 470, 482, 489) on the shoulder (414) and resisting such rotational force at the connection between the tie plate (410, 420, 440, 450, 460, 478) and the tie (20, 120, 220, 320). A steel tie for incorporation in a rail track has a horizontal oblong rectangular plate member (21, 121, 221, 321) for connection transversely of the rail, and a web (23) or webs (123, 223, 323) extending vertically on the underside of the plate member (21, 121, 221, 321) and spaced inwardly from its longer sides. A ballast engaging plate member (33, 41, 133, 233, 333) may be connected on the tie on its underside and faces generally transversely of the rail or ends of the plate (21, 121, 221, 321) may be bent downwardly.

Socle de rail pour traverse (410, 420, 440, 460, 478) en deux éléments, chacun comportant un épaulement (414) d'appui de la semelle du rail, une aile dirigée vers le bas (421) et un saillant latéral (422), et conçu pour être monté sur la partie plane (21, 121, 221, 321) d'une traverse d'acier percée de fentes, en introduisant le saillant (422) de chacun des éléments dans sa fente respective et en abaissant l'élément vers l'intérieur. Socle de rail (410, 420, 440, 450, 460, 478) muni d'épaulements (414) longitudinaux et comportant une surface d'appui tournée vers le bas, et tel que par des ouvertures pratiquées latéralement dans chacun des épaulements (414), on puisse engager un crapaud (430, 470, 482, 489) s'appuyant sur l'une des faces supérieures de la semelle du rail (416). Le dévers du rail est contrecarré par le transfert des couples au socle (410, 420, 440, 450, 460, 478), transfert qui résulte de l'engagement du crapaud (430, 470, 482, 489) dans l'épaulement (414) et de la résistance opposée au couple par la liaison socle (410, 420, 440, 450, 460, 478)/ traverse (20, 120, 220, 320). Traverse d'acier pour voie ferrée comportant une partie plane (21, 121, 221, 321) oblongue se fixant transversalement au rail et une âme (23) ou des âmes (123, 223, 323) verticales s'étendant le long de la partie plane (21, 121, 221, 321) et en retrait par rapport à ses côtés les plus longs. Plaque s'enfonçant dans le ballast (33, 41, 133, 233, 333) pouvant se fixer sous la traverse, en général perpendiculairement au rail, ou extrémités recourbées de la partie plane (21, 121, 221, 321) de la traverse assurant la même fonction.
