Specialists of Bryansk Engineering Plant have started operational tests of mainline freight diesel locomotive 2TE25AM-001 with asynchronous drive that is fitted with 20V4000R43 diesel engine by MTU (Germany).

Generally, the tests include 5000 km trial run to be supervised by MTU, BNIKTI and BMZ, the parties involved in the locomotive development. Bryansk – L’govsky Depot (Moscow Railroad) was selected as the test base. Its first trip with a 6000-ton train from Bryansk to Gomel (Belorussia) and then back to Bryansk, the locomotive started on July 6, 2012.

The locomotive was developed in BMZ and was derived from 2TE25A diesel locomotive named ‘Vityaz’. Power pack and related equipment differentiate the new locomotive from the reference model. Twenty-cylinder engine of 2TE25AM locomotive is a V-shaped four-stroke engine with an angle of 90 degrees. The engine is fitted with a turbocharger. The engine reaches its standard rating of 2700 kW (3672 hp) at 1800 rpm. Specific fuel consumption at standard engine rating is 194-208 grams per kWhr. Maintenance-free СаPoS capacitor starter system developed by MTU is used. Moreover, anti-freezing coolant is used to cool the engine instead of water, thus improving engine performance at low temperatures. 2TE25Am is equipped with autonomous preheater by Webasto allowing to keep comfort temperature of heat-transfer agents before engine startup. The new locomotive is equipped with a microprocessor control and monitoring system and locomotive safety devices.

May 31, 2012, Business Forum Partnership 1520, JSC Transmashholding and JSC Russian Railways signed a contract of delivery of 10 two-section mainline freight diesel locomotives 2TE25AM.
