摘要： A railroad fastening system that includes a see-thru (transparent or translucent) rail seat assembly which allows for immediate visual feedback to assess whether that a sufficient amount of adhesive material has been applied to a crosstie during the installation of a rail seat assembly on a crosstie to ensure a long-lasting bond and a proper cant, flatness and height of a rail seat assembly.

摘要： A pad for a railway rail fastening assembly, the pad being configured for placement between a rail and an underlying foundation, such as slab track or a sleeper, wherein a cross-section of the pad comprises: a second resilient layer configured to face a railway rail; an intermediate rigid layer; and a first resilient layer configured to face an underlying foundation. The rigid layer is provided between and is integrally formed with the first and second resilient layers. An edge of the pad comprises at least one ear that extends beyond a central region of the pad, the rigid layer extending into the ear with the ear being configured to resist rail roll.

摘要： A plate assembly for securing a rail to a tie that includes a clip and a shoulder with an orifice. At least one of the clip and the shoulder are modified by changing their respective shape to form a positive interference fit therebetween. The modification is provided to ensure that the clip is maintained with its leg partially inserted into the shoulder orifice during staging.

摘要： A fastening system or apparatus for securing a rail to the underlying railroad tie includes a pad, two insulators attached to the pads and two shoulders attached to the ties. An interference fit is formed between the insulators and the shoulders to capture the pad between the shoulders. The insulators are pre-attached to the pad. The mating protrusions of the shoulders and pad allows for ease of insertion such that the pad assembly can be shipped together with the underlying tie.

摘要： A rail pad (1), for electrically isolating a railway rail (2), comprises a rail seat portion (11) for supporting a foot of the rail (2), a pair of upstands (12) joined to opposite edges of the rail seat portion (11) of the pad (1) by respective webs such that respective channels (13) for directing water away from the rail are defined between the rail seat portion (11) of the pad (1) and each adjacent upstand (12). Such a pad provides improved wet electrical resistance.
