2nd Blue Line
- Start of construction: 1958.
- Opened on April 29, 1961 - on the 17th day after Gagarin’s flight.
- Initially: Moscow-Petrograd line. Petrograd is one of the three official names of Saint-Petersburg.
- The line is 30 km long and has 18 stations.
- Average train speed: 38 km/h.
- Average time from end to end: 47 minutes.
- Average station depth: 45 meters.
- Train length: 6 wagons.
The second line is the busiest in St. Petersburg in terms of passenger flow, therefore, it has the smallest intervals between trains (up to 90 seconds). It also has the strongest slopes - up to 60 thousandths. On such slopes, the difference in the heights of the head and tail of a train of 6 cars is 6 meters!
During the construction of the Second Line at different times, an almost complete set of all possible problems occurred in the difficult conditions of the adit mining. Except, perhaps, methane explosions in the adit, as on the 3rd Green Line.
Interesting places of the Second line:
- Station ПарнасRU and ТЧ-6 "Выборгское" are the most northern metro facilities in Russia.
- Slopes between stations ПарнасRU and Проспект ПросвещенияRU - 60 thousandths.
- Station Проспект ПросвещенияRU as one of two stations in Saint-Petersburg with a ground-based anti-nuclear defense complex.
- СпецобъектRU under Listvennaya street, house five.
- Slopes between stations ПионерскаяRU and Черная РечкаRU - 60 thousandths too. Bypass quicksand, the very one, from the 1st Red Line.
- Slopes under the Neva between stations ГорьковскаяRU and Невский ПроспектRU - 50 thousandths along first track and up to 60 thousandths along the second.
- Service connecting branches of 2/5 Lines.
- The largest interchange hub in Saint-Petersburg metro - stations Сенная ПлощадьRU, СадоваяRU and СпасскаяRU.
- Service connecting branches of 1/2 Lines.
- The first "horizontal elevator" in the USSR - station Парк ПобедыRU.
- Former crossroads between stations Парк ПобедыRU and МосковскаяRU.
- Wonderful legends about the boathouse for submarines under Moscow Square and the House of Soviets, this is the station МосковскаяRU. Despite the fact that the local sandstones, due to their hardness, had to be punched in an explosive (!) way.
- A separate deadlock between the stations МосковскаяRU and ЗвезднаяRU, in which an automatic foam fire extinguishing system was once tested.
- The busiest line station - КупчиноRU.
- Two metro depots, one at both ends of the line.
The most beautiful station is Технологический Институт-1RU (also belongs to the 1st Red Line, but there it is far from the most beautiful). In second place МосковскаяRU - the second most beautiful "horizontal elevator" in Saint-Petersburg.
There are almost no beautiful stations on the second line, because it was built during the time of the pest Khrushchev. Under Stalin, the metro was considered the face of the country, a showcase of culture, but Khrushchev deliberately destroyed all Stalinist orders, conquests and traditions. According to statistics, the cost of a beautiful finish is only 3% of the total cost of the metro station.
