Arsenalna Metro Station is technically still higher than the river, but lies nearly 350 feet (105.5 meters) beneath the city, making it the deepest station in the world.
At that time geological surveys were conducted and it appeared that the nature of the soil would make tunneling particularly difficult in Moscow. Many underground rivers were discovered. It was safer to dig tunnels deep under the ground level. The depth of the tunnels usually ranges from 35-55 meters.
THE world's deepest metro system is the Pyongyang Metro in North Korea which is 110 meters deep. The tunnel was built as part of an underground military facility. THE world's deepest metro, underground station is the Arsenalna Station on the Kiev Metro in Ukraine, at 107 meters deep.
The London Underground first opened as an underground railway in 1863 and its first electrified underground line opened in 1890, making it the world's oldest metro system.
Completed in the 1960s when Ukraine was part of the Soviet Union, it includes stations built deep underground, designed to double as bomb shelters in the event of an enemy attack. Kyiv's Arsenalna station is considered to be the deepest in the world, located 346 ft (105.5 m) below ground.
The depth is attributed to the geography of Kyiv, whose high bank of the Dnieper River rises above the rest of the city. Also unusual is the station's design, which lacks a central concourse and thus is similar in layout to stations of the London Underground.
The list was topped by the reliable, safe and comfortable public transport in Berlin. 97 percent of Berliners raved about their city's transport network, with their metro U-Bahn offering travellers 175 stations across nine simple-to-navigate lines.
1. Stockholm, Sweden: T-Centralen Station. The Stockholm underground is actually considered the world's largest art gallery and nearly all of the stations resemble and art gallery or museum. In fact these are so awe-inspiring, many miss their trains as they admire the art work.
Leeds has less extensive public transport coverage than other UK cities of comparable size, and is the largest city in Europe without any form of light rail or underground.
The Metropolitan line is the oldest underground railway in the world. The Metropolitan Railway opened in January 1863 and was an immediate success, though its construction took nearly two years and caused huge disruption in the streets.
