Two decades ago, rail innovation meant heavier steel and tougher brakes; today it’s boards, code, and data streams. In that shift from hardware to intelligence, Knorr-Bremse has made its latest bet: acquiring the duagon Group to deepen its grip on high-margin, safety-critical rail technology.
In their press release, Knorr-Bremse said the move builds out its international rail portfolio by bringing on Duagon, a Switzerland-based supplier of hardware and software for safety-related applications across the railway sector. Headquartered in Dietikon and active in Europe, North America, China, India, and Australia, duagon focuses on embedded electronics that sit at the heart of modern rolling stock and signaling systems.

The companies argue the fit is natural. Knorr-Bremse, long recognised for braking and entrance systems, expects the purchase to add a new electronics pillar while unlocking synergies in areas where it already leads. By knitting duagon’s platforms into product lines, the group aims to standardise and scale electronics architectures, improve R&D efficiency and accelerate features such as remote monitoring and diagnostics for maintenance and operations.
The deal also plugs directly into Knorr-Bremse’s specialist units Selectron (railway electronics) and KB Signaling (signaling technology). With rail networks digitalising, management believes combining duagon’s embedded solutions with those businesses can widen margins and expand addressable markets—particularly as KB Signaling takes its North American know-how global. In short, the company is positioning itself for a world where safety, communication and control run increasingly on software.
What Happens Next: Approvals, Integration, Outlook
Knorr-Bremse and the former owner, DBAG Fund VII advised by Deutsche Beteiligungs AG, have signed a sale contract; closing remains subject to regulatory approvals. The transaction targets market segments—electronics, communications, software—that are growing faster than the wider rail industry, largely due to digitalisation. Duagon’s products are designed into on-board train architectures and trackside signalling, handling safety-related information, commands, and subsystem control—areas with high entry barriers and sticky customer relationships.
Operationally, the integration plan centres on long-term platforming. By taking Duagon’s embedded building blocks and applying them across product families worldwide, Knorr-Bremse expects more uniform electronics platforms, lower cost per function in development, and stronger competitiveness. As for the innovation, management is prioritising digital services—remote condition monitoring and diagnostics—to lift availability while trimming lifecycle costs for operators.
Founded in 1995, duagon employs about 750 staff across eight countries. Knorr-Bremse cites a compound annual growth rate of 15% (2022–2025) and projects around EUR 175 million of revenue in 2026 with an operating EBIT margin of roughly 16% (before integration costs). It plans to raise profitability further through revenue growth and cost measures, and is targeting EBIT-effective run-rate synergies of EUR 5–10 million from 2028. duagon serves vehicle manufacturers, systems integrators, and rail infrastructure companies.
Marc Llistosella, Chief Executive Officer of Knorr-Bremse AG: "Our acquisition of duagon, a successful electronics supplier, demonstrates once again that we are strengthening our rail business, which will drive up profitable growth. More particularly, we are honing our technological expertise in the key areas of railway electronics and rail signaling technology, and are increasing the high-margin share of revenue in rail vehicles. The acquisition is a perfect fit with our BOOST strategy, giving us the opportunity to reinforce and build on our core competencies, but also focus on high-profit lines of business. We would like to warmly welcome Duagon’s international team and look forward to collaborating with them."
Dr. Nicolas Lange, member of the Executive Board of Knorr-Bremse AG with global responsibility for the Rail Division: "Safety, reliability, and efficiency are at the core of our DNA, which means that Duagon is a perfect match for us. In Duagon, we are gaining an expert in specialist solutions for not just embedded electronics but also communications and software solutions for trains and train tracks. Above all, Duagon’s platform solutions will allow us to increase the uniformity and scalability of our established solutions and to further improve the services we provide to our customers through digitalization. This acquisition will take Knorr-Bremse a big step closer to its goal of becoming a leading Tier 1 partner for the entire rail transport system, also with regard to electronic solutions."
Dr. Michael Goldbach, Chief Executive Officer of duagon: "With Knorr-Bremse, duagon gains a partner with whom we will strengthen and rapidly expand our position as a leading embedded electronics supplier in the rail market. We look forward to benefiting from Knorr-Bremse’s strengths and expertise, leveraging them in all business segments, and bringing our complementary expertise to the world of Knorr-Bremse. This will create an even broader range of opportunities for our customers and employees and ensure long-term stability and continuity."
