ABSTRACT:
In an apparatus for measuring the lateral distance between adjacent tracks, a measuring axle has a wheel which is selectively engageable without play with a selected rail of one track while a pivotal projecting arm associates therewith has laterally movable mounted thereon a rolling element for adjusting to the lateral distance between the measuring axle and the rolling element. The rolling element is arranged to sense one rail of the adjacent track as it rolls therealong, and an indicator produces a measuring signal indicating the adjusted lateral distance.
