German railways to use mini drones to stop graffiti
BERLIN (AFP) - Germany's railway operator plans to deploy mini drones to catch vandals who deface its trains with graffiti, with the aerial vehicles shooting thermal images of its train depots at night.
Deutsche Bahn plans to soon start testing the vehicles which have four helicopter-style rotors and can shoot high-resolution pictures.
"We are going to use this technology in problem areas, where taggers are most active," a spokesman who asked not to be named told AFP.
A "pilot" remotely steers the vehicles at heights of up to 150m and speeds of up to 54kmh. An operator evaluates the images, which the company plans to use as evidence.
