DB are hoping their new Bond-like miniature helicopters – red all over, with the DB logo - will be able to detect and film spray-painters and vandals in the act, wrote Bild am Sonntag.
The machines, which like a military drone are fitted with heat-sensitive cameras, are due to be tested over the next weeks – for now only on DB property and airspace.
If suspicious movement is detected, the operator on the ground alerts a pilot also at ground level, who can then chase down the culprits using a remote control which works up to 40 kilometres away.
The whole thing – including a log of GPS data - will be filmed so that the culprits can be later brought to justice in court, wrote the paper.
At €60,000 each, the battery-operated helicopters can fly silently for over 80 minutes at 54 km/h at a height of 150 metres, said Bild am Sonntag.
“We have to find new ways of fighting graffiti,” Gerd Neubeck, head of security at Deutsche Bahn told the paper.
