FIELD: transport.
SUBSTANCE: every car body seats on one rotary bogie. Angle between lengthwise axes of coupled cars bodies is actively influenced by controlled electric actuator unless said angle takes preset value. This preset value is defined by turn angles (relative angles) of rotary bogies relative to appropriate car bodies. In compliance with first version, said angle is adjusted by kinetic and/or potential energy of car spring suspension. In compliance with second version, force acting at coupling hinge is measured to use it for adjustment of actuator. When said force varies said angle with departure from preset magnitude, said actuator is locked or stays locked.
EFFECT: accurate and simple run over track turns.
