In conventional railroad standards the only way an alignment defect can be measured is against it “uniformity”, the question of rate of alignment change from a track infrastructure standpoint is one that is not yet answered or outlined in the industry. Our primary objective is to understand alignment rate of change in 31 ft. This includes curve spirals, connecting tracks, turnback curves, reverse curves, and turnouts. During my presentation we will enter into a collaborative structured discussion centered around track alignment and rate of change.
