Construcciones y Auxiliar de Ferrocarriles, S.A.

CAF (Construcciones y Auxiliar de Ferrocarriles, S.A.) is Spain's largest rolling stock manufacturer, headquartered in Beasain, Basque Country. Founded in 1918, the group employs about 17,788 people, generated approximately €4.22 billion of revenue in 2024 — a 10% year-on-year increase — and holds an order backlog of roughly €14.7 billion, securing multi-year capacity utilisation across its factory network. It is the world's leading supplier of mid- and low-capacity light rail systems.

Business Overview

CAF's product portfolio spans trams, metros, commuter and regional trains, intercity platforms and light rail systems. Its Urbos tram family is the global benchmark for modern light rail, with the 1,000th unit delivered in 2025, while the Civity regional platform serves European operators and custom metro fleets run in Hong Kong, Australia, Saudi Arabia, the UK and major North American cities. The group also builds locomotives and special vehicles for niche markets.

Manufacturing is organised around Spanish core plants and a distributed international network. The historic facilities in Beasain and Zaragoza handle carbody welding, painting, bogie production and final assembly, while localised plants and assembly lines in Mexico, Brazil, the US, France and Algeria allow CAF to satisfy local-content requirements in its most important export markets — a strategy that has let a mid-size Spanish company win contracts against far larger competitors.

Core Strengths

CAF's deepest competitive advantage is its light-rail franchise. The Urbos platform has become the default choice for new tram networks across Europe, the Middle East and North America, and the group's ability to configure vehicles for individual networks — from heritage city centres to modern segregated lines — is matched by few rivals. Its emerging-market position is equally valuable: strong installed bases in Hong Kong, Australia, North Africa and South America feed a growing aftermarket and modernisation pipeline.

The group's diversification into zero-emission mobility added strategic depth. Its participation in the FCH2Rail hydrogen train project and the acquisition of Solaris, Europe's leading zero-emission bus manufacturer, give CAF an integrated "rail plus road" clean-mobility offering that few competitors can match. The €14.7 billion order backlog, which includes major contracts in Saudi Arabia, the UK and the US, provides exceptional revenue visibility.

Challenges & Outlook

CAF's principal financial challenge is profitability. Net profit of €103 million in 2024 represents a margin of roughly 2.4%, reflecting aggressive pricing in international tenders and currency headwinds, while high working capital intensity on large projects can pressure cash flow between milestones. As a mid-size builder, it also depends on partners for complete signalling and control solutions in turnkey bids.

The outlook remains strongly positive. Global urbanisation keeps driving light-rail and metro procurement, emerging markets continue to spend on mass transit, and the backlog gives years of production certainty. With its flexible platforms, localised manufacturing and expanding clean-mobility portfolio, CAF is well positioned to remain the world's most successful mid-size rail equipment manufacturer.
