The vehicle consists of 5 car bodies which rest on two motor bogies and one trailer bogie.
The motor bogies are equipped with two longitudinally- mounted motors, each of which powers an axle via an angular gearbox. A spring-applied brake caliper HYS 106 is positioned between motor and gearbox which acts on the fast-moving brake disc. Brake pad wear is compensated by an automatic slack adjuster which is integrated into the spring-applied actuator. The two spring-applied actuators are proportionally controlled via a hydraulic power unit HZY-K100-DPR with emergency braking function. The HEY-C brake control unit converts the braking signals of the train control unit into corresponding signals to the hydraulic power unit.
In the trailer bogie, each axle is braked by two exterior HYS 258 spring-applied actuators. Proportional activation with slide-protection monitoring is performed for both axles via a hydraulic power unit HZYK140- PR with emergency braking function and external pressure accumulator which in turn receives its signals from a HEY-C brake control unit.
All bogies have an auxiliary release pump in order to be able to manually release the spring-applied actuators via a second hydraulic circuit which is independent of the service circuit in the event of a malfunction. Safe release / engagement of the spring-applied actuators concerned is signalled via a pressure switch.
