This Japanese train barks and snorts to protect deer from harm

Researchers from the Railway Technical Research Institute (RTRI) in Japan have equipped a train with a speaker that plays the sounds of dogs barking and deer snorting to persuade deer to scramble off the train tracks, away from any oncoming train. A three-second deer snort is played first to catch the attention of any nearby deer, followed by twenty seconds of dog barking to scare the animals away.
