The Hakone Tozan Line is Japan's first mountain railroad. It is operated by the Hakone Tozan Railway. This company belongs to the Odakyū Group, and also owns the Hakone Tozan Cable Car.
The initial stretch of the line from Odawara Station to Hakone-Yumoto Station started operations in 1919, with current terminus Gōra reached in 1930. Since 2006, only Odakyū Odawara Line trains run on the previously dual-gauge section from Odawara Station to Hakone-Yumoto Station. From Gora, visitors can continue up the mountain on the Hakone Tozan Cable Car.
The railroad is capable of climbing one meter vertically for every 12.5 meters of horizontal distance, a maximum slope of 8%. The line traverses Fuji-Hakone-Izu National Park, so the line was carefully designed to limit the impact on scenery. Due to the difficult conditions, the line has three switchbacks used to ascend particularly tight spots.
・・・さて、最後の信号所。 ココで（あまり停車時間がないので速やかにっ）聞いてみましょう。 "Do you think that this train goes in which direction?"
