In Japan , growing cervid population are causing clash on the railways . The issue of deer hit by trains each class is increase , so the Railway Technical Research Institute has come up with a novel idea for curbing the problem , according to theBBC . Researchers there are using the sound of barking dog to scare cervid away from danger zones when train are approaching , preventing power train equipment casualty , delays , and of course , deer carnage .
It ’s not your standard automobile horn . In pilottests , Japanese researcher have bond speakers that blare out a combining of sounds designed specifically to ward off cervid . First , the recording captures the animals ’ attention by playing a snorting phone that deer use as an “ alarum call ” to warn others of danger . Then , the phone of howling dogs drive the cervid off from the caterpillar track so the train can elapse .
Before this enterprise , the job of deer congregation on string track seemed intractable . Despite the best efforts of railways , the animals are n’t deterred by ropes , barrier , show off lights , or even Leo the Lion feces meant to repel them . Kintetsu Railway has had some success withultrasonic wavesalong its Osaka bloodline , but manyrail companiesare still struggling to shell out with the emergence . Deer flock to railroad tracks for theiron filingsthat voltaic pile up on the rails , using the smoothing iron as a dietary supplement . ( They have also been known to figure out Ernst Boris Chain link fence . )
The new deer - deter soundtrack is particularly useful because it ’s relatively low - tech and would be cheap to implement . Unlike the supersonic plan , it does n’t have to be set up in a particular post or require a lot of young equipment . dally through a speaker on the train , it goes wherever the train goes , and can be deploy whenever necessary . One speaker on each railroad train could do the job for a wholerailwayline .
The researcher found that the recordings they designed could reduce the number of deer sighting near the gearing track by as much as 45 percentage during winter nights , which typically see the high-pitched collision rates . According to the BBC , the noise will only be used in unpopulated field , reducing the theory that people living near the train track will have to endure the sound of frump howling every Nox for the rest of their lives .
Deer are n’t the only animals that Japanese railways have sought to protect against the dangers of railroad track tracks . In 2015 , the Suma Aqualife Park and the West Japan Railway Company teamed up tocreate tunnelsthat could serve as safe rail crossings for the turtles that kept getting hit by trains .
