ADJUSTABLE RAILWAY RAIL FASTENING ASSEMBLY AND METHODS FOR USE THEREWITH

摘要

An anchoring device (4), for retaining a spring rail clip (3) in a railway rail fastening assembly, comprises an anchoring stem part (40), fixed to a rail foundation (2) when the device is in use, and a clip-retaining head part (41), engageable with the said anchoring stem part (40), for retaining the spring rail clip (3), the height of the rail clip (3) relative to the rail foundation (2) being determined by the position of the clip-retaining head part (41) of the device (4) relative to the anchoring stem part (40) thereof. Adjustment of the position of the said clip-retaining head part (41) relative to the said anchoring stem part (40) is effected by translational movement of the clip-retaining head part (41). In a method of adjusting lateral rail position in a rail fastening assembly using such an anchoring device (4), the clip-retaining head part (41) of at least one of the anchoring devices (4) in the rail fastening assembly is replaced by another clip-retaining head part (41') having an overall thickness, at a portion lying between the rail foot and the anchoring stem part (40) of the device (4), which differs from that of the first-mentioned clip-retaining head part (41).
