Abstract. Fibre optic sensors are excellent tools to use for monitoring high-voltage current collectors. Because of their small cross section and electrical neutrality, they are easily integrated into the current collector strip and are well specialized for detection of high-speed load events. The conventional contact force measurement with four force sensors below the collector strips can also be simplified by using fibre optic force and acceleration sensors.

Short summary
Fibre optic sensors are excellent tools for monitoring (with) high-voltage current collectors. They are easily integrated into the collector strip and specialized for detection of events like hits on the strip. The sensing system can be used in regular trains and make monitoring of the overhead contact line routine, which is done "along the way", helping not only to prevent accidents by small intruders, but also allowing the prediction of wear and is used to optimize service and repair cycles.
