A PROTOTYPE MAINTENANCE-0F-WAY PLANNING SYSTEM. VOLUME IV: VALIDATION OF THE PROTOTYPE MOW PLANNING SYSTEM

The past Track Quality Indices (TQI's) and prediction equations of the Maintenance-of-Way (MOW) Program were analyzed from a validation standpoint by reviewing track degradation, residual analysis, and regression analysis in 124 unmaintained track segments. The results of this study supported many of the concepts of the prototype maintenance-of-way planning system; however some concepts were contradicted. It should be pointed out that this study was based on a somewhat different and smaller test zone than in earlier studies. This study used a test zone with less traffic, more curves, and predominantly continuously welded rail. Track geometry data was measured by the FRA T-6 track geometry vehicle.
