PRELIMINARY FIELD EVALUATION OF A TRACK STRENGTH TEST VEHICLE

This report presents the results of a preliminary field evaluation of the Track Strength Test Vehicle, the Decarotor. The objectives of this test series are to define the capabilities and limitations of the test vehicle and to examine the capabilities of the system to measure track strength and identify "weak" track of yard quality. The test results indicated that the system could successfully and repeatedly identify weaknesses in the track section such as poor joints or groups of ties in "poor" condition. It was further noted that these tests could be performed at increasing speeds and without significant damage to the track structure.
