ABSTRACT OF THE DISCLOSURE A measuring carriage for measuring the undulations and ripples of a worn rail head running surface is guided along the rail head by a pair of guide rollers laterally guiding the carriage along a portion of the gage side of the rail head which is not worn and a plurality of addi- tional guide rollers selectively engageable with the run- ning surface of the rail head for vertically guiding the measuring carriage along the running surface upon engage- ment therewith. The additional guide rollers include a pair of inner guide rollers, a pair of outer guide rollers and a pair of intermediate guide rollers spaced from each other in the operating direction. The pair of outer guide rollers defines a rigid measuring reference in the wave length of the longer undulations and they are spaced from each other a distance of 2 m. A respective lateral pair of the inner or intermediate guide rollers is selectively engaged with the running surface to define a rigid measur- ing reference in the shorter wave length of the ripples and these rollers are spaced from each other at least about 1/6th to 1/8th of the first-mentioned distance. A rail head running surface sensing element is vertically adjustably mounted on the measuring carriage substantially centered between the pairs of guide rollers.
