    摘要: A special trackwork fastener (10) for supporting a railroad rail and attaching it to a support structure. The trackwork fastener (10) is modularly constructed and includes a top plate (20), resilient end portions (12) and (16), optional resilient center portion (14), and securing elements (18). The special trackwork fastener (10) has the versatility to be used in a large number of special trackwork situations such as turnouts, crossovers, crossings and switches or the like, which require a variety of lengths of trackwork fastener (10). The vertical compression stiffness and adjustability in length is provided by two opposed end portions (12),(16) and an optional center portion (14) which is molded or cut to length such that the portions collectively match the length of the top plate (20) and therefore the top plate (20) is fully supported along its length. The elastomer portions can be cored out to provide the desired compression stiffness.

    摘要: A rail-support insulating device for electrically insulating a rapid transit rail and rail fastener from the rail support structure is described. The device includes an electrically non-conductive member that surrounds and extends outwardly from the rail fastener and over its support structure. Also a pair of planar disc members of similar material extend around and outwardly from the heads of the mounting bolts for the rail fastener, thereby forming long surface electrical creepage paths between the rail and the rail support that provide electrical isolation even when the entire assembly of rail fastener and rail support is wet with electrolyte.
