Well, there are two types of escalators known in Russia as "tunnel escalators" (which are operate at deep-level Metro stations) and "floor escalators" (which are operate at shallow Metro stations as well as in many trade stores, office buildings, etc). Of course, there are special demands on the reliability of "tunnel escalators".

During last 10 years, there exist only one main manufacturer of escalators for Russian Metro systems - ELES Plant in St. Petersburg. However, during last five years there opened many stations in Russia. As a result, they received more orders and were no able to produce escalators in time for few times. On several occasions, the opening of new Russian Metro stations and reopening of old Russian Metro stations after reconstruction was been postponed on few months because necessary escalator parts were not delivered in time.

There only not so many Western companies that produce "tunnel escalators" for deep-level Metro stations. Also, Russian technical requirements are specific - due to location at deep depths, the speed of these escalators must be faster. As you can understand, if Western companies will produce "tunnel escalators" for deep-level Russian Metro station, it would be much expensive - the one deal is serial production and another deal is specific order.

There were some attempts to attract other manufacturers for producing of "floor escalators". In 2008-2009 in St. Petersburg Metro were installed new escalators in two transfer corridors between new Metro station "Spasskaya" and old Metro stations - "Sadovaya" and "Sennaya Ploshchad". These escalators were manufactured by Kirov Plant (St. Petersburg) in cooperation with LLC "Constructor" according to the design of Head Constructor Viktor Khristich. This case became notorious - due to general problems in its design, it took a lot of time for installation of these escalators. But after one year since the opening of Metro station, engineer were forced to spend another 8 months for repairment of broken escalators. I already wrote about this situation in this thread:
http://www.skyscrapercity.com/showth...#post100440325

As you can see, Khristich's escalators in Nizhny Novgorod Metro were fully replaced. For all these reasons, Khristich's escalators were contemptuously nicknamed "Khristolators" ("Christolators").

In contrast, there are no Russian-made escalators in Kazan Metro. Two Metro stations in Kazan are equipped by escalators made by "ThyssenKrupp AG", one station - by escalators made by "Otis Elevator Company" (there are no escalators at other 7 Kazan Metro stations).

Thanks. Recently Euro-standards led to some speed-limits for escalators. Metro Pragues new escalators are probably slower than the original russian ones because of that. Top speed can be 0,75 m/s, but I guess in that case the escalator has to have a longer plain running part at the top and at the beginning, like you have in deep-level-stations.

In Germany itīs 0,5 m/s or 0,65 m/s. This also depends on german regulations (you can be stricter than EU if a country wants to). But german stations are not that deep. Personally I think that 0,65 m/s is a boring ride if it comes to deep-level stations. Otherwise Pragues escalators had a higher accident-rate in the past.

Kind regards

The first models of Soviet escalators had nominal speed of 0,75 m/s. In mid-1950s it was decided to increase speed. They started to produce escalators with nominal speed of 0,9 m/s, since 1970s - 0,94 m/s. The escalators of first models were also modified in order to operate with such speeds (there were replaced motors). Such speeds were quite comfortable for passengers, but it led to increasing of noice, wear and cost of repairment. In Soviet times, there were no problems with funding of repairment works. However, in terrible 1990s, the funding was greatly limited. As a result, the speed of all escalators was decreased to 0,75 m/s (however, some old escalators still operates with higher speed). According to new Russian standarts, the nominal speed of new escalators should be no more than 0,75 m/s.

The "floor escalators" can has lesser speed. For example, there are installed escalators with nominal speeds of 0,5 m/s and 0,65 m/s at the stations of Moscow Monorail and Butovskaya Light Metro Line. The escalators made by "ThyssenKrupp AG" also operates with same speeds.

I don't think that "much expensive". On "Sportivnaya" in St. Petersburg will be installed ThyssenKrupp tunnel escalators. So it's not a problem, if customer wants.

Well, construction of second vestibule of Metro station "Sportivnaya" ("Sportive"; Line 5; opened on September 15, 1997) in St. Petersburg (at the other bank of Malaya Neva River) is very interesting project. There will be installed 6 travelators (for first time in Russian Metro systems), 4 big escalators (length - 40 m) and 4 short escalators (length - 20 m). "ThyssenKrupp AG" won tender because they promised to built all necessary equipment in time - till early 2015 (as I wrote, ELES had problems with terms). They will produce 6 travelators "Orinoco" and 8 escalators "Victoria" (the cost of this equipment is 16 mln. Euros). I'm not sure about 40-m escalators, but it's seem that it will be "floor escalators" with nominal speed of 0,65 m/s. As I understand, the passenger traffic in the second vestibule will be not so high as at the some other deep-level stations of St. Petersburg Metro.

As I wrote, "floor escalators" made by "ThyssenKrupp AG" are already operates at Russian Metros - in Kazan and Nizhny Novgorod. Recently, Moscow authorities ordered "floor escalators" for future Metro station "Delovoy Tsentr" ("Business Center"; Line 8) which planned to be opened this year. Also, there will be installed "floor escalators" made by "ThyssenKrupp AG" at the second vestibule of Metro station "Park Pobedy" ("Victory Park"; Line 3; opened on May 6, 2003) - the deepest station in Moscow Metro. However, it will be only short escalators for vestibule while the longest "tunnel escalators" will be made in Russia.

The vestibule will be decorated with mosaic panels which depicts daily life of the nearest Hay Square in 19th century. According to main idea of architects, passengers will be look at these mosaic panels like at the historical Hay Square through imaginary windows of vestibule:
