Odakyu Hakone Co.,Ltd. (Former Hakone Tozan Railway Co., Ltd.)

In 1872, Japan's first railroad line opens between Shimbashi and Yokohama.
In 1889, The Tokaido Line is now in full service on its route from Koudu to Numazu via Gotemba.
The Odawara Basha Railway Co., Ltd. was established by volunteers in Odawara, which had prospered as a major post town on the Tokaido route since the opening of Edo, and the horse-drawn railroad between Koudu and Yumoto was opened in 1888.
After that, construction of a power plant and electrification work were carried out, and in 1900, the Odawara Electric Railway began operating the entire line between Koudu and Yumoto, replacing the horse-drawn railway.
n response to a strong recommendation that a mountain railroad should be built to attract tourists to the scenic Hakone area, Odawara Electric Railway conducted a survey of actual conditions in Europe and the United States.
As a result, the adhesion rail system was adopted instead of the abt system(Using Rack-Pinion gear), and by installing switchback lines at three locations, the 8.9-kilometer Hakone Railway between Hakone-Yumoto and Gora began operation on June 1, 1919.
Also, in 1924, the gauge (track width) was changed to the standard (1435 mm). Furthermore, in 1921, a steel cable railway (cable car) from Gora was opened.

Nose suspension drive

Trains run by transmitting the rotation of the main electric motor to the axles, turning the wheels. Since the speed of the main electric motor is too fast to be transmitted directly to the wheels, a pinion gear is attached to the motor and a large gear to the axle so that the motor turns several times and the wheels turn once.
One side of the main electric motor was hanging from the axle, so the driving sound that would be heard when the train ran was transmitted directly to the seats, bringing nostalgia to the guests.
