ABSTRACT:
An instrument for measuring railroad track geometry for a pair of tracks. e instrument includes a carriage having wheels for permitting the carriage to ride on one of the tracks. An elongated cross-level bar has one end mounted on the carriage and the other end joined to a roller assembly. The roller assembly supports a pair of measuring wheels that ride on the top of the other track. A plurality of sensors are mounted on the bar for sensing the gage and cross-level of said tracks, and for measuring the linear distance that the instrument moves with respect to the tracks. A removable handle, hinged to the cross-level bar, supports a digital read-out meter for displaying the gage, cross-level and distance traversed.
