Power saving. 
As a result of the introduction of the asynchronous traction drive of wagons, the daily cost reduction of electric energy is 1,276 kWh, which is 40% of the daily amount of current electricity consumed by one 5-car train. Given the total number of upgraded trains, the expected reduction in daily electricity costs will be 14% of the total daily electricity consumption. energies of all compounds on the line. In accordance with the results of the traction and energy tests of the experimental train, the cost of consuming electric the energy of 5 carriages is 25.7 W * h / t * km. Daily amount of used email. energy one 5-car modernized train is 1549070.92 Wh, which is 82% of the daily consumed electric. energy of a modernized train without recovery. Thus, the recovery of email. energy during electrodynamic braking will be 18%.
