FIELD EVALUATION OF MAINLINE QUALITY TRACK, USING A TRACK STRENGTH TEST VEHICLE

Results of the field test of the prototype Track Strength Test Vehicle, the Decarotor, on mainline track are reported. This part of the ongoing Track Strength Characterization Program is directed at measuring the load-carrying capacity of track structures, at development of suitable measurement techniques, at determining usefulness of such measurement and at matching track strength with vehicle loading. It was shown that continuous strength measurements are feasible and can consistently identify track weaknesses such as clusters of poor ties. Nondestructive tests from a moving vehicle can evaluate long stretches of track. Stationary load deflection tests can identify condition of ties or rail fasteners. Further work is necessary to demonstrate the practical value of the testing techniques.
