摘要：
Railways defects such as broken rail endangers the safety of railway operations. In order to ensure the railway safety and a secured travel we present a method for monitoring railways. Our purpose is to obtain a proof of concept, monitoring system for the rail that can be trusty, accurate and has the potential to be used remotely. In this work an extensive sets of experiments has been performed in order to analyze the possibility of using optical fiber sensors for monitoring railways. The investigations refers to the behavior of optical fiber sensors response to temperature and strain changes in order to evaluate railway expansion.
