MODELING GAUGE STRENGTH DEGRADATION FROM TLV TEST RESULTS

Predicting railroad track degradation can help lead to reductions in railroad operating costs by allowing for scheduling and prioritizing of track maintenance work. There are a number of factors that influence track gauge strength degradation, such as curvature, grade, fastener type, tie type, accumulated tonnage, and track age. This article describes research looking at degradation rates and behavior for these factors, and the development of a degradation equation. Results show that wood tie track degrades more quickly in eastern part of the U.S. than the western part, this being primarily due to the higher overall precipitation and humidity in the East. Accumulated tonnage and curvature are the next two most prominent effects on degradation rate.
