SUBSTANCE: invention relates to the field of the superstructure of the railway track, in particular to the arrows for the rail track. The switch contains rails and sleepers. The rails are fixed on sleepers in pairs. Intermediate layers are laid between the rail and the sleeper. Elastomeric soles are located on the lower sides of the sleepers. The midsole layers comprise at least one elastomeric layer. The elastomeric sleeper layer of each of the sleepers has at least two areas of different softness. The harder area is located under the first rail and the softer area is under the second. The rails are fixed on the top side of each sleeper. The softness of the intermediate elastomeric layer located between the first rail and the sleeper differs from the softness of the layer between the second rail and the sleeper.
