CAF Power & Automation

What CAF Power & Automation does

CAF Power & Automation is a Spain-based railway propulsion and components manufacturer founded in 2012 and operating as a division within publicly listed CAF Group (Construcciones y Auxiliar de Ferrocarriles, S.A.). The company designs and manufactures electric traction systems including DC and AC converters, traction motors, transformers, filtering inductances and braking resistors, alongside energy storage systems under the GREENTECH brand, hydrogen and lithium-ion battery propulsion (OESS), and a proprietary Train Control and Management System called TCMS COSMOS. Its components portfolio extends to wheels, axles, elastic wheels, gearboxes, and fully mounted axle solutions, with over 50 years of gear reducer manufacturing heritage.

The business sells through direct enterprise B2B field sales targeting three primary customer segments: passenger rail operators and transit authorities (high-speed, regional, commuter, metro, light rail), freight railway operators, and train OEMs. Revenue derives from hardware sales of propulsion and component systems, modernization and retrofit upgrades for existing locomotives, proactive maintenance and support services delivered across 35+ countries, and advisory services for end-of-life component recycling. Pricing is quote-based and not publicly disclosed, consistent with complex, customized B2B industrial procurement.

CAF Power & Automation competes on the basis of vertical integration (internal manufacturing of key components), a large installed base (5,000+ converter boxes, 12,000+ AC traction motors, 15+ million km of battery operation), and a global service network spanning the Americas, Europe, Africa and Asia-Pacific. Its product roadmap is oriented toward rail decarbonization through battery, hydrogen and hybrid propulsion for non-electrified routes, positioning it within the broader rolling stock power conversion market projected to grow from USD 5.66B in 2025 to USD 8.00B by 2034.

Core offering

CAF Power & Automation designs and manufactures electric traction systems (DC/AC converters, traction motors, transformers), energy storage systems (GREENTECH), hydrogen and lithium-ion battery propulsion, Train Control and Management System (TCMS COSMOS), and railway components (wheels, axles, gearboxes, mounted axles). The company also provides maintenance services and end-of-life recycling solutions for railway operators, train manufacturers, and freight companies globally.

Product overview

CAF Power & Automation operates as a multi-module platform specializing in railway propulsion, components and digital systems. The portfolio centers on electric and hydrogen-based traction systems (Sistemas de tracción eléctrica, Soluciones de propulsión AC) as the core platform, complemented by proprietary energy storage solutions (GREENTECH, Tecnología de baterías de hidrógeno, Baterías de propulsión de Ión-Litio) and train management systems (TCMS COSMOS, Sistemas de control y comunicación). The offering is extended with manufactured components (Ruedas, Ejes, Ruedas elásticas, Reductoras, Ejes montados) and services (Soluciones de mantenimiento, Soluciones para el final de la vida útil). This integrated approach allows CAF to deliver complete propulsion chains from traction converters through motors, transformers and wheels to end-of-life recycling, positioning the company as a full-system provider rather than a single-product vendor.
