Rail fastening devices
摘要:
A rail tie plate suitable for attachment to a wood tie has a pair of upstanding abutment members to accommodate a rail flange, each having an upwardly facing lower ramp surface inclining from a laterally outer side of the abutment member upwardly inwardly to a laterally inner side to facilitate insertion of a rail clip. The tie plate tapers in thickness and has an upper side canted with respect to the lower side. The lower side is provided with wedge shaped projections that tapers laterally in the same direction as the plate and have an end face making an angle no greater than 90° with respect to the lower side.
