Abstract
A rail arrangement includes a bullheaded rail having joint ties and a rail head, a rail bridge and a rail foot. There is a driving track made of concrete with an integrated joint, in which the rail is seated in connection with a substrate; as well as profiles made of elastomeric material. The profiles includes a base profile arranged below the foot of the rail and which has flanges on both sides which completely or partially grip around the foot of the rail. The base profile has a plurality of channels having a rhombic cross-sectional shape and extending in the longitudinal direction of the rail, which are arranged in the plane extending parallel with the underside of the foot of the rail. The channels at the edges of the base profile have a smaller cross sectional shape than the channels at the center area. There are two side profiles abutting the rail on both sides. One of the side profiles preferably has a tracking groove on the side of the wheel rim. There is also a joint tie coating.
