ZDS 1 is a specialized road-rail vehicle developed for emergency response operations on railway and tram networks, primarily focused on rerailing derailed rolling stock. It is equipped with a high-capacity hydraulic crane, stabilization systems, and dedicated lifting accessories that allow operators to safely raise, reposition, and accurately place wagons or trams back onto the track. The vehicle is designed to operate in demanding field conditions where fast and controlled intervention is critical to restoring traffic flow.
Its configuration may include a separate operator cabin for precise crane control, technical storage space for recovery tools, and additional support systems required during accident response. ZDS 1 is typically used by railway emergency and maintenance services responsible for infrastructure protection, incident management, and rapid restoration of operational continuity after derailments or mechanical failures.
