FIELD: railway track superstructure.

SUBSTANCE: invention relates to the field of the superstructure of the railway track, in particular to electrical insulating butt gaskets. The gasket contains a head, a neck and a base and follows the contour of the cross-section of the rail joint. The spacer is formed from a deformation-resistant support flat base and an elastic coating on the surfaces. The gasket is equipped with a resiliently movable insert. The edge of the insert protrudes above the gasket head. The insert is in contact with the wheels and with the support base. There is a layer of elastic cover between the insert and the base.
