81-72x are classic cars. Original were produced in 1990's. Serial production (.1 modification) was in 2002-2003. They operates on LDL 10 and KahL 11. Made in late 1980's - early 1990's they were technologically outdated. So the project was canceled in favor of new 81-74x, as back then there was no necessity of traditional cars.

Lines 4 FL and L1 BL were small capacity and mainly surface/elevated with small (relatively, down to 200m) radius curves, so required a new cars made specially to operate in all local climatic conditions. ~14m sections of each car reduced wearing and improved speed in curves.

APL 4 wasn't that busy as TLK 6, SPL 9, KRL 7 and KolL 5. And Kol'tsevaya Line 5 is operated by 6-car 81-71x series trainsets, so a new 6-door 81-741.4 (intermediate car) and 5-door 81-740.4 (head car) modification was made to replace them in 4-car trainsets.

81-76x stands to replace old 8-car trainsets operates on busy lines. It first probably go to Kalininsko-Solntsevkaya Line 8, if 81-714.6 and 81-717.6 will be canceled.

Then, when you say standard cars, what's the difference between the 81-72x and the old cars from the 70s and 80s and the new 76x? Are they all the same size? And was the 72x a new developement or just the old trains modernized and with new front? Do I understand the chronic right, if I understand that the 72x was a new developement to replace old 717/718 trains, but due to economics of the 90s could never be produced, and now is too old and outdated so that they made a completely new design, the 76x?

yet again - all modifications have same series number with added .N ending. modifications of 81-71x were .1, .2, .3, .4, .5 and latest dated from 2009 .6.

81-72x was a new train developed in 1980's - early 1990's to replace 81-71x series. Two modifications A and .1 were made lately.

Comparing 81-76x to 81-72x - 81-76x is all new train with new chassis, new engine, new concept ways of forming interior, new doors, electronics. 81-76x have almost nothing from 81-72x. It's mainly built with experience of 81-74x series. 81-72x was new to 81-71x as well, but it was made with technologies of 1980's.
there is the original or A
http://transit.parovoz.com/muralista...ID=3565&LNG=EN

and there is .1
http://transit.parovoz.com/muralista...ID=3559&LNG=EN
http://transit.parovoz.com/muralista...D=12477&LNG=EN
http://skyscrapers.ru/gallery/v/coth..._3248.jpg.html

Head car for 81-717 is 81-714. 81-718 is a head car for 81-719. It was updated model of 81-714/81-717 built in 1992 with a new engine, ventilation, reduced energy consumption and some more advantages. But they were not used in Moscow Metro as they were more expensive than 81-714.5/81-717.5.

Thanks for the confirmation, that's exactly what I thought!
Good explanation and clarification.

Recently I occasionaly took a ride on a new Russich train which was the most up-to-date modification.
It has more doors that the previous one, which is much better for the service taking into account the number of passngers getting on and off.

But the most important thing about it was that it was armed with air conditionning. It was not simple forced ventilation (which is still good progress for Moscow trains) but a good and effective system of air-conditioning. I was really pleased, the ride was very comfortable.

Some pics taken on Park Pobedy station.








30.06.2010.

By the way, the signals above the doors are new as well, different from those on previous trains.

Sublime

What kind of vision and respect to offer the people access to such elegance.

Are newer stations anything close to the ones shown in this video?

That is very important reason why ridership is so huge. It is very important for people to don't feel uncomfortable deep underground.

Are there no elevators from overground to the platform, so that disabled persons get easier access? Quite sad if there aren't.

Yeah, that's kind of stupid. They should build them no matter where. What are people in a wheelchair supposed to do if they need to drive to that station? It's not like building an elevator when you're building a whole new station is any challenge or extra effort. I don't know why, but I always thaught in Russia they pay extra attention to those in need.

When the station is 60m deep, escalator is 120m long and you have to go more than 100m deep into tunnel out of station to get to the elevators shaft under the entrance.

Not if you build an inclinator alongside the escalators, they use this solution in Stockholm for example.
