A Novel Method for Railway Crossing Monitoring Based on Ambient Vibration Caused by Train-Track Interaction

Railway crossings are critical components in the rail network. They usually degrade faster than the other components. It is therefore vital to monitor their conditions using appropriate methods. This paper proposes to use the ambient vibration caused by the train-track interaction from a distance to monitor the condition of railway crossings....

In situ measurements of the crossing vibrations of a railway turnout

Vibration-based condition monitoring is a powerful tool for remotely assessing the quality of railway components. Due to its design, railway crossings suffer from faster degradation, because of the transition from stock rail onto the needle. Since this is also a repetitive load, a small amount of wear will increase the degradation. Measuring...
