The very efficient railways of the Land of the Rising Sun are always a step ahead: it is difficult, in fact, to find a country where trains are more technological and efficient. Lately, however, are the deer that cross the tracks to create some problems with the punctual Japanese cars.
Thus, a group of researchers from the Tokyo Railway Technical Research Institute tried to develop new technologies to scare animals and keep them away from the tracks.
The system designed will allow the trains to imitate the sounds of dog barking and other ways that should keep the animals away. Although it may seem an unusual and funny solution, tests on some trains have shown a reduction of 45% of deer sightings.
The tests included 3 seconds of deer brambles and 20 seconds of dog barking. Despite the well-known punctuality of the Japanese trains, there would not be rare delays and suspensions in the mountain areas due to collisions with animals. The authors hope to make the system operational by March 2019.
