Abstract

Burlington Northern Railroad's track geometry measuring car is described along with the techniques and equipment on the car that are used to measure absolute and relative deviations in track geometry. The key parameters being measured are described as well as the methods used to obtain the measurements. The test platform is a passenger coach weighing 110 tons with 3 axle trucks. One of the trucks is instrumented with linear displacement transducers, a tacometer, and laser optics. Track geometry measurements are made at one foot increments along the track and rail profile measurements are at 15 foot increments. Track geometry data is processed in real time at speeds up to 60 mph. Rail profiles can be produced in real time to a limited extent, most of the profile data is post processed. Examples are shown of the real time and post processed track geometry and rail profile reports that are currently produced from meassurement data.
