duagon, which has its registered office in the Swiss city of Dietikon, was established in 1995 and has since become a leading independent provider of network components for data communication in railway vehicles. The company’s products allow individual railway vehicle systems, such as doors, brakes, air conditioning systems and the primary control computer, to communicate via what is known as the TCN (“train communication network”). This makes it easier to integrate these systems into the train manufacturers’ networks and limits sources of errors in the process. This allows suppliers to concentrate on their core competencies, namely the development of the individual railway vehicle components. duagon products are used by virtually all train manufacturers and system suppliers.

duagon has developed long-standing customer relationships and broad-based technological expertise in its niche market. Its strong competitive position and the very positive market drivers provide an ideal environment for above-average growth.

Potential for development

duagon has established strong relationships with customers in China, the world’s largest market for railway vehicles, over the last ten years. In order to further exploit growth potential with Chinese customers, the company intends to further expand its local sales network, R&D capacities and supporting functions. India and Japan are additional major railway markets that duagon is targeting by establishing a local sales presence. duagon aims to establish itself as a specialist in providing solutions for data communication in railway vehicles by offering a broader product portfolio and via acquisitions in both the immediate and extended competitive environment. With the acquisition of MEN Mikro Elektronik in May 2018, duagon gained a foothold in mission-critical, rugged computing solutions predominantly for the railway, but also medtech and similarly complex critical automation applications.
