FIELD: construction; transportation.
SUBSTANCE: invention relates to the accommodation of rail supports and can be used in the carcase of sleepers. Concrete sleepers, which are prestressed, have an outhang located under the rail base. Base of foundation of the outhang is buckled and has at least two bezels. Two bezels, when intersected with each other, form an angle in the range of 180° up to 90° and are symmetrically arranged relative to longitudinal axis of the outhang.
EFFECT: as a result, the amount of engineering works on surfacing in the longitudinal profile of assembled rails and sleepers, stabilization of ballast bed is ensured immediately after packing-up or renewing the track, the original location of gauge remains unchanged under any train load.
