German Railways to Test Anti-Graffiti Drones
The purpose of the drones is to use infra-red cameras to collect evidence in order to prosecute vandals.
The drones would be tested at rail depots soon, however, it is unclear how Germany’s anti-surveillance law will affect their use in a country where using cameras to film people is a sensitive issue, and where privacy is very highly valued.
Deutsche Bahn spends about 7.6m euros (£6.5m; $10m) a year on graffiti removal.
Each drone will cost about 60,000 euros and fly almost silently, up to 150m (495ft) above ground.
