Abstract

This paper reports on the first fiber-optic temperature measurement of overhead contact line systems at a new ICE3 high speed line of the German Railway. The installation of Fiber Bragg Grating (FBG) sensors, the online acquisition and interrogation of data over a one year period is presented. Keywords: Fiber Bragg Grating, temperature monitoring, overhead contact line, catenary, power management. 1 Introduction All railway companies try to achieve higher reliability and flexibility in train service. As a consequence the quality of train control processes as well as monitoring equipment for the next generation of high speed railway lines needs to be improved. Next generation of high speed trains will consume more power, because of an increased amount of ele
