the development of rail transport in the russian federation.the development of электроподвижного composition in russia began in 1930, then was issued the first domestic electric locomotive dc вл19. figure 19 is the load on the axle. second is the initials of vladimir lenin. in 1950 began electrification, roads in shock. the first electric locomotive designed for these roads was вл60. passenger электровозы in russia produced, purchased in czechoslovakia and riga. in 1975, the вагоностроительным started august 14 15 электропоездов dc er200 with structurally speed 200 km / h. such electric designed for passenger traffic in high-speed railways currently runs on the line to st. petersburg and moscow. in recent years, russia is developing a new электроподвижного composition, modern. since 1994, a number of railways, electrified at a constant dc operated commuter trains production демиховского (эд2т) and торжокского (эт2) carriage building factories. and since 1996, operated by electric alternating current эд9т. in 1997, демиховском вагоностроительном factory started producing электропоездов ed4 and эд4м. on the тихвинском factory "трансмаш» built the first electric train" сокол», a maximum speed of 250 km / h. in 2003, completed the establishment of a new generation of electric эм4 "спутник». on the новочеркасском электровозостроительном factory in двухтысячных, started producing new electric locomotives of the electric locomotive ep1, эп2, эп100 and эп300. now carried out research work on the development of a new generation of электропоездов asynchronous traction motors and the pulse control of high-speed movement.another promising development system is the system электроподвижного of dc high voltage.the high voltage will be reduced at the expense of a loss in the transfer of energy, in addition to the direct current power quality no problem, which is a variable d.c. voltage.
