Hi Gary, hi all, thanks for starting this topic!
It had to be strange if I wouldn't appear here, right?
First useful link can be brief official info about Soviet and Russian railways in English, available at the site of RZD - Russian State Railways Company:
http://eng.rzd.ru/static...c/rzdeng?STRUCTURE_ID=30Also I guess that some selected (by me) facts about Soviet railways would be interesting for all of you since we really, really had (and still have) great railway history, extensive railways network, interesting loco designs and much more!
Here is my choice. Lets start from my favoutite heavy and high speed-steam locomotives.
In the beginning of 1930s Soviet government decided to use the U.S. experience (which was actually great) in designing and building of the first Soviet heavy freight steam locomotive. Both countries had quite similar conditions of locomotive service: long distances, high speeds, heavy trains, similar landscape. Therefore in 1931 Soviets bought the U.S. heavy freight steamers Ta and Tb, all necessary working drawings and built heavy freight steamer FD, heavily borrowed from its American brothers.
American influence is obvious in this and other heavy steam locomotive designs of the Soviet Union.
FD (Felix Dzerzhinsky) Heavy Freight Steam Locomotive. Built in 1931-1942 (3213 machines). Load per axle up to 22t, power output up to 3100 HP. Used until 1960s, in the beginning of 1960s around 1000 engines granted to China and North Korea.

IS or IS20 (Iosif Stalin) became passenger derivative of FD and the most powerfull
serially built Soviet steam locomotive. Built in 1932-1942 (629 machines). Load per axle up to 20t, power output up to 3200 HP, maximum speed up to 115 km/h. Used until beginning of 1960s, few engines until 1972.
Immaculate looking machine, what to add, was favourite loco of the most Soviet loco engineers.


In 1937 streamliner version of IS20 (IS20-16) was built. 155 km/h speed achieved during test runs. Tests didn't go ahead since railtrack on the most territory of the country was not ready for such high-speed service.

However, high-speed experiments continued with this amazing steam locomotive:

Unusually looking streamliner of the type 2-3-2b (so called steamer #6998) was built in 1938 using parts of FD and IS. Main wheel diameter was 2,2 meter, maximum planned speed 180 km/h. Engine has been widely tested before and after WWII in Ukraine and part of Moscow-Leningrad line.
In 1957 2-3-2b set the speed record for Soviet steam locomotives - 175 km/h.

In 1950s the last steam locomotive constructions in the USSR appeared.
1. P36 fast passenger steam locomotive. 251 machines of this type built in 1950-1956. Maximum speed up to 125 km/h. Maximum power output 3077 HP. Finally retired in 1974, this very powerful and reliable engines had to sidestep to diesels and electrics.

2. P38 extra heavy freight steam locomotive. 4 engines built in 1954-1955.
The heaviest and the most powerful Soviet steam locomotive. Mallet design construction. Load per axle 20t, service weight of the loco up to 214t, service weight of the tender with coal and water up to 168t,
total weight up to 383t, power output up to 3800 HP.
These monsters tested in 1955-1959, including complicated landscapes and severe climatic conditions of Siberia.
Simply Soviet Big Boy!
Just very few photos left.
In February 1956 Soviet government decided
to stop all developments related to steam locos and to concentrate on the railways electrification and building of electric and diesel locomotives.

Soviet high-speed steam locomotives:
Note that IS20-16 streamliner is running at the speed about 130 km/h and being filmed from Polikarpov U-2 Soviet bi-plane aircraft flying at about 110 km/h. So the spectators would think the steamer is faster than the airplane!
On the occasion of
175th anniversary of Russian railways (celebrated in September 2012) great loco parade took place at Shcherbinka RZD test facility near Moscow on September 7, 2012. Here you can see some of the
main types of the Soviet and Russian (from 10th minute) locomotives.
Thankfully, with the help of some sponsors and railway enthusiasts, many historical locos in recent years were restored to operational condition. Its great!
Thanks for reading and viewing, all the best, Andrey.
