TMH completes 2ES5S locomotive test run

A freight electric locomotive class 2ES5S manufactured by Novocherkassk Electric Locomotive Plant, part of Transmashholding, has successfully completed its 5000 km test run at Railway Research Institute.
During the run, the locomotive confirmed its full compliance with technical requirements. The latter included verification of the traction system characteristics at speeds of 0 to 120 km/h carrying a rake weighing 6900 tonnes.
Currently, the locomotive is being prepared for the certification trials, after which it will leave for East-Siberian Railroad, Taishet-Taksimo stretch to undergo operational trials. Its hauling capabilities, overall reliability, as well as working conditions of the crew, will be tested in real life conditions with a rake of 6500 tonnes.
The eight-axis freight electric locomotive with asynchronous traction class 2ES5S is a new iteration of class 2ES5 developed by Transmashholding together with Alstom. The vehicle boasts an autopilot, encrypted radio communication, and preemptive self-diagnostics with registry logging. The implemented technical solutions ensure maximum power output and efficiency, optimal hauling cost, and a lifecycle increase of 18%.
Compared to 2ES5, this new locomotive carries a number of upgraded components such as a traction inverter, an auxiliary drive, traction motors, a traction transformer with compressor equipment, bogies, and control system components. 85% is the share of Russian-made components used for the production of this locomotive.
