<p>The rail (1) has a ramp (3) formed from a point of wheel contact of the rail by a small hollow-running wheel (6) approximately upto a point of a theoretical wheel overflow. The hollow running wheel is transferred to the rail by a core (2). The ramp runs on a surface of the rail. The depth of the ramp at the point corresponds to the hollow-shape measurement of hollow-running wheel profiles. The ramp is sloped in a direction of the core.</p> |
