摘要： A pad for interposition between the bottom of a railway rail and a rail foundation upon which the rail stands is a single piece of elastomeric material in the form of a substantially rectangular sheet with substantially rectangular cut-outs at the center of two opposite sides and chamfering of at least the upper major face at the other two opposite sides. In a rail and fastening assembly projections which extend upwardly from the rail foundation, and are engaged by means holding the rail down, lie partly in the cut-outs and impede movement of the pad along the rail.

摘要： A tie plate is formed with a profile defining two parallel protrusions with bores for receiving the respective ends of two clips. The two clips engage the flange of a rail to secure the rail to the plate, and therefore, to tie disposed below the plate. Since the protrusions are made integrally with the the plate, the resulting tie plate is able to support the rail securely even in the presence of large forces and/or twisting moments on the rail resulting from a train passing over the plate.

摘要翻译： 连接板形成有限定两个具有孔的平行突起的轮廓，用于接收两个夹子的相应端部。 两个夹子接合轨道的凸缘以将轨道固定到板上，并且因此固定在板下方。 由于突起与板一体制成，所以得到的连接板能够牢固地支撑导轨，即使在由列车通过板的过程中导致的轨道上存在大的力和/或扭矩的情况下。

摘要： A rail clip is made by bending a metal bar so that one end of the bar is one end of a straight portion of the clip, further portions of the clip lead to a portion which crosses the axis of said straight portion near said one end and the other end of the bar appears to be substantially perpendicular to said straight portion. The clip can bear on a fish plate at a joint between two rails.
摘要翻译： 轨道夹是通过弯曲金属杆制成的，使得杆的一端是夹子的直线部分的一端，夹子的另外部分引导到靠近所述一端与所述直线部分的轴线交叉的部分， 条的另一端似乎基本上垂直于所述直线部分。 夹子可以承载在两个轨道之间的接头处的鱼板上。
