ABSTRACT Foot support modifications are required in the vicinity of rail attachment devices used in track systems. The rail attachment devices are arranged on ties or appropriate track- retaining elements and have at least a sole plate (8), for example, a ribbed plate or only one shim without a ribbed plate, which is seated on the top of the tie or the like and is connected to this through carriage bolts or the like. In order to achieve a non-tipping position of the railroad line, the rail foot support area (12) of the sole plate (8) or of the shim is provided only with flat bearing surfaces (15 and 16) that extend in the form of two strips and lateral sections (13 and 14) that are each associated to the two longitudinal edge zones of the rail foot, whereas the lateral section (17) that is located between them has a shaped face (18) that is set back relative to their common plane. Even if the supporting surface of the rail foot of the railroad line does not coincide exactly with a proscribed standard plane but has a contour that projects convexly above this, a non- tipping position of the railroad rail on the sole plate or the shims is ensured by these measures.
