ABB’s PMA® TRUST™ modular support system was adopted by Alstom Spain for cable routing in Citadis™ trams due to its flexibility, compactness, and compliance with EN 45545-2 railway safety standards. It enables safe and efficient installation of various conduit sizes in space-constrained, weather-exposed tram roofs. The system minimizes installation time and ensures secure fixation with high reliability. ABB and Alstom’s long-standing partnership enabled co-design of a modular solution tailored for rolling stock, helping streamline operations and enhance safety and sustainability in modern rail transport.
