The BBC reports that Germany's national railway company, Deutsche Bahn, plans to test small drones to try to reduce the amount of graffiti being sprayed on its property. The idea is to use airborne infra-red cameras to collect evidence, which could then be used to prosecute vandals who deface property at night.
A company spokesman said drones would be tested at rail depots soon. But it is not yet clear how Germany's strict anti-surveillance laws might affect their use.
Graffiti is reported to cost Deutsche Bahn about 7.6m euros (£6.5m; $10m) a year.
As a matter of interest, and in an effort to compare the cost in the UK, National Rail indicate they spend more than £3.5 million a year removing graffiti. Their responsibility includes the 17 of the major rail stations in the UK but not the remaining 2,500 railway stations which are managed by the train operating companies. Added to this would be the cost of removing grafitti from rolling stock.
