The development of railway transport in Russia.
The development of electric rolling stock in Russia began in 1930, then it was released the first domestic electric DC VL19. The number 19 mean axle load. HVL initials of Vladimir Lenin. In the 1950s began the electrification of road ac. The first electric locomotive intended for these roads was VL60. Passenger locomotives not produced in Russia, they have purchased in Czechoslovakia and Riga. In 1975, the Riga Carriage Works started production of 14 electric train ER200 DC, with design speed of 200 km / h. Such electric designed for passenger transport on high-speed railways, now ply on the line St. Petersburg-Moscow. In recent years, Russia has carried out the development of new electric rolling stock that meets modern requirements. Since 1994, a number of railroads electrified DC, suburban trains operated production Demikhov (ED2T) and Torzhok (ET2) Carriage Works. And since 1996, operated by an electric AC ED9T. In 1997 Demikhovsky wagon factory started production of electric and ED4 ED4M. Tikhvin factory "Transmash" built the first electric train "Sokol", designed for speeds up to 250 km / h. In 2003, it completed the creation of a new generation of electric EM4 "Sputnik". In Novocherkassk Electric Locomotive Plant in two thousandth's started production of the new series of electric locomotives EP1, EP2, EP100 and FL300. Now conducted research work on creating a new generation of electric trains with asynchronous traction motors and high-speed pulse-controlled.
Another promising development system is a system of electric rolling DC high voltage.
In this case, due to a higher voltage will be reduced transmission losses, and in addition, no dc power quality problems, which are ac.
