FIELD: construction.
SUBSTANCE: invention relates to device for railway track superstructure, to rail fastening device to its base. Anchor rail fastening comprises anchor (1), which lower part is concreted in under-rail base (2), upper parts of anchors (1) are made in the form of post (3) with hook-like retainers (4) facing the rail from the position of spring terminals (5) in form of helical springs, having engagement segment (6), located between helical sections (7), which end with support sections (8) retaining rail (9) in design position, pressing its bottom through rubber-cord gasket (10) to under-rail base (2).
EFFECT: as a result, assembling and dismantling of fastening is simplified, it becomes possible to perform complex technological works on track maintenance without violation of integrity of rail-and-sleeper grid.
