This paper 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 magnitudes and vibration frequencies in the frequency domain. The results show tracks with good tie support display tie accelerations below 5 g and small vertical displacements during train loading whereas approaches with poor tie support display accelerations generally greater than 5 g. These results are used to evaluate other transition zones and identify problematic track locations that require repair procedures to retain acceptable track geometry.
