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.
