The accurate prediction of the wheel / rail contact geometry is significant importance in railway vehicle dynamic simulations for the safety, the running stability, the curve negotiation performance and so on. However, the experimental validation of the contact geometry results comparing to the theoretical results in various kinds of the condition monitoring all the time has not been performed. In this study, a new methodology for the measurement of the wheel / rail contact geometry will be introduced. For the validation of the proposed method, experiments to measure stress with the wheel / rail contact using embedded FBG sensors were done. Then, it is successful to get the data of the distributed strain inside the rail due to the real load of the wheel / rail contact.
