A railway rail anchoring device, for use with a railway rail-fastening clip which is approximately M-shaped in plan and has first and second leg portions and a rail-bearing portion, comprises a base member and first and second clip-retaining members connected together by the base member such that the first clip-retaining member is spaced apart from the second clip-retaining member so as to define between the first and second clip-retaining members an opening for receiving the rail-bearing portion of such a clip. Each of the first and second clip-retaining members defines a passageway for receiving one of the leg portions of such a clip, and a boundary surface of at least one of the passageways includes, at a location intermediate respective ends of the passageway, first locating part for engagement, when the device is in use with such a clip, with a first region of the leg portion of the clip located in the passageway such that the clip can be held in a pre-assembly position in which the is retained by the device but the rail-bearing portion of the clip does not bear on a rail. Second locating part is also provided on a boundary surface of at least one of the passageways for engagement with a second region of the leg portion of the clip located in the passageway such that the clip can be held in a working position in which the rail-bearing portion of the clip bears on the rail. The first and second locating parts are such that the clip cannot move out of the pre-assembly position towards a rail unless driven in a first direction and the clip cannot move out of the working position away from the rail unless driven in a second direction, opposite to the first direction.
A railway rail anchoring device, for use with a railway rail-fastening clip which is approximately M-shaped in plan and has first and second leg portions and a rail-bearing portion, the device comprising:
A rail fastening assembly comprising a railway rail fastening clip suitable for holding down a railway rail, and an anchoring device, the clip being formed of a rod of material bent such that the clip is approximately M-shaped in plan, having first and second leg portions formed to cooperate with part of the anchoring device so as to locate the clip in the anchoring device, and also having a rail-bearing portion formed between the first and second leg portions, the anchoring device comprising:
