VL80R
Designed for use along the difficult sections of the Krasnoyarsk, Eastern Siberia, and Far Eastern routes – as well as the "Батайск" (en: Bataysk) depot in the North Caucasus – the VL80R (ru: ВЛ80Р) has the same tractive capabilities as the VL80T and the VL80S. The difference between the VL80R and the two aforementioned models is that it has an improved anti-wheelslip system which continuously regulates the amount of voltage supplied to the traction engines, thus ensuring that an increase in thrust doesn't result in jerks, which invariably lead to wheelslip. The VL80R gets its R designation from the fact that it is fitted with regenerative braking (ru: рекуперативное торможение) mechanism.
Several locomotives, assigned to the Krasnoyarsk section, have been modernised and are capable of participating in MU operations with consists containing 3 coupled units.
Despite having been in production for almost 20 years (1967-1986), a mere 373 examples rolled out of the NEVZ plant.
