Investigation of longitudinal profile of rigid frogs on reinforced concrete sleepers

Abstract

In the paper the effect of longitudinal profile of rigid frogs of type R65 mark 1/11 on reinforced concrete sleepers on the interaction in the ‘wheel-rail’ system in the zone of rolling surface irregularities is investigated.
