Abstract(s)

Rail temperatures play an important role when understanding and predicting rail track instabilities. A rail temperature energy balance model was used, validated with FEA analysis, and compared with field-collected data. Both simplified and Finite Element Analysis (FEA) model are in good agreement. Compared with the collected data, the model reaches an R² of 0.83. Boundary conditions improvements are needed.
