The main component of all electric locomotives of the Suramipass is the presence of a transition at the end of the superstructure, which was the standard at the time for all electric locomotives with electrical equipment for working with multiple controls in the SŽD . Perhaps this design was also determined by the existence of the normal pulling and buffing device at the time, consisting of screw couplings and buffers ; the vehicles were only later equipped with central buffer couplings.

The vehicle part consisted of two articulated three-axle bogies with the wheel arrangement Co 'Co'. The superstructures were designed as wagons with load-bearing main frames. The suspension was preferably designed with leaf springs . The suspension of the traction motors was carried out according to the paw-bearing drive .
