duagon, Dietikon (Switzerland)

Embedded electronics for railway, medtech and critical automation applications


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.
