Abstract
The apparatus includes a parallelogram-like foldable frame, opposite corners of which carry centering rollers to position the frame between two opposite track rollers; feelers measure the distance to the latter. The frame can be hung between the tracks or can be self-propelled by a belt drive. Some of the centering rollers can be used for reeling tests of the track rollers.
