Diesel mainline freight locomotive 2TE25A-012 "Vitayaz" ("Knight").
First 2TE25A was built in 2006 by BMZ (Bryansky works). Its design is based on type 2TE25K, but incorporates modern solutions, such as AC/AC transmission, individual axle traction control and anisochronous traction motors.
15 locomotives have been built so far (including modification 2TE25AM). They operate on DVZhD (Far-Eastern railway, Tynda depot) and on MZhD (Moskovskaya railway, Bryansk depot).
