摘要：

In recent years, Fiber Bragg Grating (FBG) sensors have been attracted a lot of interest, and widely and increasingly researched in many important areas. In this work, we present the field of railway dynamic monitor concerning the application of FBG sensors. We have built the principle and established the sensing system based on FBG to monitor the situation of train and railway through the analysis of track strain during the train passage. We have illustrated that FBG sensors set on the lateral and underside of the rail can detect the strain of rail and sensors on different positions show distinct results. We have presented that the underside of the rail structure is the most suitable position to monitor the strain in railway.
