Road-rail vehicle equipped with a railway drive system of two types:
1) K-RR-32.WF-1 – friction type;
2) K-RR-32.HD-1 – hydrostatic type.

The vehicle is manufactured on the base of the VOLVO automobile chassis and is a ready-made technical solution for the production of road-rail machines on its basis for repair and construction of the upper structure of the railway track. The mentioned vehicle can be used as a base for overhead catenary maintenance and construction machines, mobile rail welding complexes, construction machines, etc.

The vehicle is equipped with the necessary systems for movement by railway. Two types of the drive of movement on rail are manufactured: a friction type (from driving wheels of the automobile chassis) and a hydrostatic type (from the hydromotors installed on the axles of the railway bogies).
