Wheelset Diagnosis for High Speed Traffic

High speed traffic requires enhanced supervision of wheelsets. For this purpose, an installation for wheelset diagnosis was set up in the ICE depot at Hamburg-Eidelstedt. Cracks in the running surface are located by means of ultrasound; wheelset dimensions are determined using the light-slice method; and wheelsets are examined for eccentricity with the aid of a measuring bar. Experience gained in the development and the placing into service of this installation is reported.
