1. An anchoring assembly for fastening a railway rail to an underlying foundation; the anchoring assembly comprising:
a base plate configured to receive the rail;
a fastener configured to fasten the base plate to the underlying foundation; and
a rigid sleeve defining a passage through which a stem of the fastener passes,
wherein the base plate comprises an opening and the sleeve is configured to extend through the base plate opening,
wherein the sleeve extends a distance greater than a thickness of the base plate such that the sleeve extends from a top surface of the base plate and beyond a bottom surface of the base plate when installed,
wherein the sleeve is configured such that a compressive load applied by the fastener when installed is transmitted through the sleeve to the underlying foundation, and
wherein the sleeve passage extends in a direction perpendicular to a longitudinal axis of the fastener when installed such that the lateral position of the sleeve and base plate relative to the underlying foundation is adjustable.
