FIELD: railway transport; continuous checking condition of rail gauge parameters. SUBSTANCE: with vehicle rolling along track which has two turnable running bogies, angles between axles of bogies and axle of vehicle are measured, and clearance in gauge between wheel flange and inner side of rail head is determined. Running bogies are forced in position in which pneumatic cylinder is set with maximum cocking, and total number of angle measurements between bogies axles and vehicle axle should exceed number of measurements of the angles when vehicle is displaced through distance equal to its base B. EFFECT: provision of determining track gauge on straight sections of tracks and in easement and circular curves. 2 dwg
