The train was not made for the tourist at the beginning. The railway was constructed in 1923 to transport the materials to build water power station. It was shorter distance and all the route was completed in 1937.

Because there were a lot of requests from the tourists who want to go to the gorge, they transformed the line for the tourists in 1953. It has been operated by the subsidiary company of Kansai Electric Company.

The railway

You can start the railway tour from Unazuki. The name Kurobe Gorge Railway in Japanese is Kurobe Kyokoku Torokko Densha. Torokko means small train and Densha means electric train. Some carts doesn’t have walls and windows, so you can feel the air. On a sunny day, you will feel very comfortable. You can also choose the carts with walls and windows by paying a little extra fee.

The train goes very slowly to enjoy the view. Though the total length of the line is about 20 km, it takes 80 minutes one way if you go to Keyakidaira, the last stop of the line. The train goes through 21 tunnels and 41 bridges.

Followings are the spots along the route.

There is the Kurobe Dam which was constructed along the Kurobe River near Unazuki for the electric power plant.

At a height of 60 meters and a length of 64 meters, Atobiki Bridge spans the steepest and deepest valley along the rail line.
