In Japan haben sie vor, Züge mit Sounds ausstatten, die bellende Hunde imitieren, um somit Hirsche und Rehe von den Gleisbetten zu vertreiben und Kollisionen zu vermeiden: Japanese train barks like a dog to prevent accidents.
Die Meldung ist schon was älter, keine Ahnung, wie weit die mit dieser Idee aktuell sind.
Researchers in Japan have fitted a train with a speaker that barks like a dog and snorts like a deer in order to prevent collisions on the railway. Tokyo’s Asahi Shimbun newspaper reports that the combination of sounds is designed to scare deer away from the tracks in a bid to reduce the number of animal deaths on the railway.
Officials from the Railway Technical Research Institute (RTRI) say that a three-second blast of the sound of a deer snorting attracts the animals’ attention, and 20 seconds of dog barking is enough to make them take flight.
RTRI researchers say the late-night tests, at times when deer congregate around railway tracks, have resulted in a halving of deer sightings. If proved to be effective, future plans include static barking sites where deer are commonly seen, but “the noises will not be blared in areas where people live beside the tracks”.
