German railways to test anti-graffiti drones

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.
