A fleet of miniature helicopter drones mounted with thermal imaging cameras will be deployed to combat graffiti-spraying gangs on the German railway network.
The drones, which fly at an altitude of 150 yards, will be used at graffiti ‘hotspots’ such as the big German cities of Berlin, Leipzig, Cologne and Hamburg, a spokesman for Deutsche Bahn confirmed.
The use of drones against vandals is the latest indication of the growing civilian market for unmanned aerial reconnaissance. Over 400 new drone systems are being developed by firms based in Europe, according to an EU report published last September.
The drones used by Deutsche Bahn cost 60,000 euros each and are manufactured by German firm Microdrones, which also markets the machines for landscape photography, analysing traffic accidents and monitoring crops.
