A class ChS2T electric locomotive is a huge machine. They were a design by Škoda Works of Czechoslovakia, built 1971-99. The type is used by the Russian and Ukrainian state railways and the very similar ChS4 type also by the Belarus state railways. ChS2 is the DC current version and the same locomotive for AC power is ChS4. The basic design of the locomotive is already from the 1950s but the version in this picture was produced in Plzen at the V.I.Lenin plant of Škoda since 1971.

Two class EP1 electric locomotives in front of an express train. The model EP1 has been built in three series by the Nowotscherkassk locomotive factories since 1999. It is a six axle (three two axle bogies) machine for 25kV AC generating 4400 kW of power.

The class EP1M is a further development of the earlier and wide spread class EP1 shown above. These EP1M locomotives have been produced by the Novotscherkassk factories since 2006. Here it is seen hauling a night train from Izhevsk to Nishny Novgorod.

A class EP20 new electric locomotive in front of a Talgo train, ready to leave towards Moscow. The EP20 machines are built by Transmashholding's Novocherkassk Electric Locomotive Plant and they are jointly developed by Alstom and Transmashholding. The basic technology in the locomotive is French.

A fixed Talgo train composition. Talgo is a Spanish company, which has for many years been producing these fixed train compositions, so called Talgo trains. The coaches are shorter than normal and instead of normal bogies, the coaches have just individual axles which are adjustable so that the train can adapt itself to various gauge widths. These Russian Talgo trains can run on both Western European normal gauge 1435 mm tracks as well as Russian broad gauge 1520 mm.

The axles of Talgo trains are located between the short coaches and they are adjustable in width.

The Russian state railways RZD uses the marketing name Strizh (swallow) for its low-floor, high-speed Talgo trains. They are used between Nizhny Novgorod and Moscow as well as Berlin (Germany) and Moscow.

Talgo train compositions have specialised generator coaches at their ends so that the train's air conditioning as well as the kitchen machinery work even when no locomotive is connected to the train.

A new regional train, this is the so called "Lastochka". It is a train designed by Siemens, based on the Siemens model Desiro ML (mainline). The initial Lastochkas were made by Siemens in Germany, but more have also been produced in Russia by Ural Locomotives. The Lastochkas come in five varieties (number after type indicates no. of seats/places): ES1 regional: 449, ES1 intercity: 340, ES2G suburban: 386, ES2G city-urban: 346, ES2GP intercity: 326. ES2G and ES2GP versions are made in Russia and for 3kV DC only.
This train is of the initial type ES1, made by Siemens. Picture from Petrozavodsk (Petroskoi) station 10.7.2015 by Timo Varshukov.

The same Siemens Es1 train as in the picture above, but seen from a bridge over the rails.

Still the same five coach Siemens Es1 train as in the pictures above.

Passengers queueing to get in into a class ED9M electric commuter train. ED9M is a 25 kV AC type with a top speed of 130 km/h, built by the Demichowo factories. This is a purely short-haul commuter train. In the background the same Es1 unit as in the pictures above can be seen and quite next to the ED9M a blue TEM2 diesel is pushing some express train coaches onto the platform behind.
Picture from Petrozavodsk (Petroskoi) station 10.7.2015 by Timo Varshukov.

In 2008 these same ED9M trains were still in their original blue colours and the Moscow to Murmansk express train coaches were also dark green as they used to be throughout the communist times.

This class ER2 local commuter train is already a very old train, but it has apparently very recently gotten a new painting. These units were built in the beginning of the 1960s at the factory RVR in Riga, Latvia. The round form of the front tells that this is one of the very earliest ER2s, all the newer ones have a more modern front design. A similar train with its original green communist time painting and with its original wooden hard furniture inside is displayed at the railway museum in Riga. For a picture, see the section of Latvia in this archive.

This is how most of the ER2 "Elektriscka" trains look like, with a bit more modern front than in the picture above.
