Laboratory Investigation of Track Gauge Widening Characteristics

摘要

This report describes test procedures and results of the ARR rack guage widening tests. The test included static and dynamic lateral rail loadings under various vertical and longitudinal loads, relative effects of single and double axle guage widening and single axle dynamic guage widening under a range of applied vertical loads. These tests were conducted to study the effects of progressive track damage, due to guage widening, to determine if non-destructive guage widening field tests are feasibile and if so, the best vertical and lateral loads to be used for testing purposes. This results of these tests indicate that non-destructive gauge widening testing is possible, and that the predamaged condition of the track can be measured and evaluated.
