Abstract
A track gauger includes a vertically movable gauger frame having a pair of fixed rail gauge bars extending between the rails upon a lowering of the frame. The gauger frame lies crosswise relative to the frame of a rail vehicle on which it is mounted, and outer edges of the bars are spaced apart in this crosswise direction a fixed distance for establishing a predetermined rail gauge distance. Pivotable rail gauge levers on the gauger frame engage the rails for gauging them at such predetermined distance upon engagement between the rails and the outer edges of the gauge bars. A track pre-gauger is mounted on the front end of the vehicle frame for pre-gauging the rails at such predetermined rail gauge distance.
