Evaluating the Effects of Variable Tie Support at Railway Bridge Transitions

This report compares the behavior of three different railway bridge transition zones to illustrate how poor tie support affects track performance. The three bridge transitions consist of a high-speed passenger line, a freight line, and a spur track. All bridge transitions were instrumented with accelerometers that allow tie support and track performance to be non-invasively evaluated by analyzing the measured acceleration magnitude and vibration frequencies in the frequency domain. Instrumenting and comparing both well- and poorly supported bridge approaches resulted in the development of a criterion for how railway bridge transition zones ideally should perform and allow evaluation of other track transitions. The desired outcome of this and future investigations is to improve the understanding of the movements and forces generated in poorly-supported track and identify effective track design and remedial measures.
