The pylon station
is a type of deep underground
station. The basic
distinguishing characteristic of the pylon station is the manner of
division of the central hall from the station tunnels
The pylon station consists of three separate halls, separated from
each other by a row of pylons with passages between them. The
independence of the halls allows the architectural form of the
central and side halls to be differentiated. This was especially
characteristic for stations built in the 1960s, when as a result of
the policy of "total economy," the side halls and tunnel walls were
significantly poorer than the central hall.
Building stations of the pylon type is preferable in difficult
geological situations, as such a station is better able to oppose
earth pressure. However, the limited number of narrow passages
limits the throughput between the halls.
The pylon station was the earliest type of deep underground
station. One variation is the so-called "London-style station." In
such stations the central hall is reduced to the size of an
anteroom, leading to the inclined walkway or elevators. In some
cases the anteroom is also the base of the escalators. In the countries of
the former USSR there is
currently only one such station: Arsenalna in Kiev.
Moscow there were such stations, but they since been
rebuilt: Lubyanka and Chistiye Prudy are now ordinary pylon stations, and Paveletskaya-Radialnaya is now a column
Moscow Metro, typical pylon station are
Kievskaya-Koltsevaya, Smolenskaya of the Arbatsko-Pokrovskaya line, Oktyabrskaya-Koltsevaya, and others.
Saint Petersburg Metro, pylon
stations include Ploshchad Lenina,
Vorota, and others.
