MAUZIN TRACK INSPECTION CAR

This vehicle was designed to detect measure and record graphically all variations in true alignment, top and cross-level and curvature of the running rails under loaded conditions. The French National Railways have built three of these cars; two are in constant use in France and the third works regularly outside France. The equipment consists of a special eight-wheel bogie, situated midway between the normal running four-wheel bogies of the vehicle and sharing equally the weight of the vehicle. Thus a total of 16 wheels is available to form a reference plane and detect all vertical variation. Similarly, six disc-mounted feeler shoes which follow the contour of the running edge of the rail reveal any lateral displacement of the track. Vertical irregularities on each line of rails are detected by recording the difference between the height of one wheel and the average height of all eight wheels on that side of the vehicle. Alignment is determined from versines which are measured on each line of rails over a 10 m. chord by means of three disc-mounted feeler shoes bearing laterally against the rails. Gauge is measured by two disc feeler shoes bearing on opposite rails at two points on a line at right angles to the center line of the track. Variations are measured full scale.
