This time we head out into the mountains via the famous Oigawa railway. This line follows the Oi river (Oigawa in japanese) and is made up of two sections. The lower section is built to japanese standards (3'6" track gauge, full railway loading gauge), whilst the upper part is of the same track gauge, but has a much smaller loading gauge. The Oigawa Railway is famous for being a kind of operational railway museum. The company has several steam locos, which operate seasonal tourist trains and the normal services are run by a wide variety of EMUs aquired 2nd hand from various railways across Japan.
