A rail (11) for electric railways, in particular tramways, is elastically embedded in a substructure (40). The electric insulation of the rail (11) with respect to the substructure (40) is adhesively applied to the rail surface by spraying in the form of an elastic, flexibily curing and volume-compressible and shear-flexible layer (20). The total thickness (25) of the layer (20) is at least 4 mm. The outer face (30) of the layer (20) is structured in such a way that it is adhesively joined with the substructure by bonding or a form-fit connection.
