... railroad ballast vertical acceleration loading pulse rest time SmartRock rebound vibration Abstract Railroad ballast serves to transfer moving train loads to the subgrade and maintain track stability. The profile of repeated train loading is observed to be irregular and periodical...

... highway rail grade crossing ballasted track vibration sensor machine learning RNN LSTM Abstract Highway-rail grade crossings (HRGCs) play an essential role in ensuring the secure traversal of road users across railway tracks. However, despite their significance, they present safety...

... temperature is below or above, respectively, the RNT. Mismanagement of RNT can lead to rail fracture or buckling when thermal stresses exceed the limits of rail steel. In this work, we propose an effective RNT estimation method structured around four hypotheses. The work leverages field-collected vibration...
