The West Japan Railway Company came up with the turtle-saving solution in partnership with Suma Aqualife Park in Kobe, after a spate of turtle fatalities, caused by turtles getting caught in the tracks, Metro UK reports.
The Suma park attracts thousands of visitors by train each year. It is also only a short distance from the ocean, which means a significant amount of turtle traffic across the tracks during May to September, when turtles (and tourists) are most active.
So, turtle escape routes were installed earlier this year along the tracks.
Metro UK added that, at least 10 turtles have been spotted making use of their tunnels over the summer months.
Which means at least 10 turtles saved from being crushed under trains or trapped between switch points.
