Deep Fusion Station

A deep- laid station is a station laid at such a depth at which it is constructed in a closed manner without opening the ground surface ^[1] .

A deep-laid station is a station located at a depth of more than 20 meters from the rail head ^[2] ; such a station is connected with the vestibule by an inclined course with escalators . The construction of such a station is carried out, most often, through a shaft , then tunnels are led to the station, and at the last stage a vestibule with a sloping passage is constructed.

Among the stations of the deep foundation stand out:

• pylon
• column
• single vaulted
• bunk interchange single-vaulted
• closed type ("horizontal lift")

The deepest in the world is the Kiev Metro Arsenalnaya station, which was opened in 1960 (depth of laying is 105.5 meters).
