With the onset of World War II activities of railways became regulated regulations of the State Defense Committee (SDC), the Central Committee of the CPSU (b), the Soviet government, the Supreme Command, the People's Commissariat.

The challenges facing the railways in wartime:

increase bandwidth traffic,

martial schedule transportation,

ensuring operational human, supply, medical evacuation and transportation,

construction of new roads from the rear to the front, as well as belt road.

June 23, 1941 at 44 railway was introduced military train schedule, which aims to reduce to a minimum the passenger, the unification of weighted norms of military trains and transports, etc. Measures have been taken to enhance the protection of objects kept confidential shipping documents and other information.

Four times a day the road was reported in the People's Commissariat of promoting military echelons. Following the critical levels monitored hourly.

Performance of military graphics, timely supply of all necessary to the front was the most important thing of all workers of railroads, and worked on the frontline lines and in the rear.

From the outset, the war, the People's Commissariat of Railways and used effective methods of traffic control:

widely practiced skipping trains to bypass the congested areas and directions,

to increase the capacity introduced one-way traffic,

use of motion graphics package helped supply a large number of empty cars to the point of loading and quickly take stock from the field of mass discharge

prioritize delivery of critical loads in various directions,

was organized formation of high-speed trains and driving,

bezottsepochny repair of rolling stock.

In addition, strongly supports the initiative of drivers, vodivshih heavy trains plying without replenishment of fuel and water.

In areas where it concentrated especially many trains practiced doubling compositions. On some days in some areas coupled went 40-50% of all trains. Applied and "live" lock: along a kilometer of each other to arrange a chain whistle. Once freed of land lying ahead, the engineer immediately received a signal: "You can follow along." This allowed the trains "caravans" at intervals of a few minutes. Use other methods of operative management in transportation.

Trans-Siberian Railway was the main railway of the country.

History knows no more examples of smooth transport in such difficult circumstances and in such volumes.
