Railway Solutions by duagon
duagon provides advanced solutions designed to enhance safety, efficiency, and reliability in railway operations worldwide.
Modern vehicles for public transportation, whether by rail or road, rely on sophisticated control, monitoring, and information systems. These systems manage essential functions such as condition-based monitoring and maintenance, air conditioning and heating, traction and brake control, door control, lighting, and powerpack management.
To enable seamless communication, vehicle gateways provide a unified communication platform. Onboard solutions include real-time passenger information based on current vehicle positions, infotainment, and automated fare collection. These systems support satellite positioning, wireless communication, data logging, and retrieval while integrating seamlessly with embedded electronic systems.
Given the challenging and compact environments of transportation applications, robust and compact computers are essential. These systems are typically networked via fieldbuses such as MVB, WTB, CAN, and Real-Time Ethernet (including TRDP, PROFINET, and CIP) and increasingly through safe Ethernet variants.
To meet the stringent environmental and quality standards required for rail and road transportation, duagon adheres to proven technologies, components, and methodologies. Our solutions comply with critical standards such as EN 50155 for railways, ISO 7637-2 for automotive (E-mark), and SIL 4 capabilities for safety-critical applications.
Products in Rail Applications
Robust computers are essential for modern rail technology. Digital systems perform functions in the train and on the track that are largely responsible for safety and comfort. At the same time, they are more interconnected than ever before and offer IoT interfaces for intelligent applications for train manufacturers and operators as well as passengers. This is why cyber security is also becoming increasingly important.
Computers specifically for rail technology are an important component of train control systems, for example. They meet the highest safety requirements and ensure that train operations are continuously safer and more efficient. In signaling technology, they control track vacancy detection systems, signals and signal boxes and thus also contribute to smooth and safe operation.
If they are used in communication applications, they ensure safe and seamless interaction between the train and the track (train-to-ground interaction) and establish wireless communication paths such as WLAN and 5G in trains and systems. They also enable (automated) loudspeaker announcements that improve passenger comfort and ensure operational safety in the event of activated emergency protocols.
Other key areas of application include energy management functions such as heating, ventilation and air conditioning (HVAC) or lighting. Robust computer systems are also essential for comfort functions and control real-time information displays or seat reservation systems, for example.

Safe Control and Robust Cybersecurity in Rail Systems
In rail and transport applications, ensuring safe control and strong cybersecurity is essential to maintaining operational integrity and protecting against threats. The integration of modular embedded computers, especially DIN rail-mounted systems, is vital in achieving these objectives. These specialized systems enable real-time monitoring and control of critical railway operations, such as signaling, communication, onboard systems, and infrastructure management.
Safe control mechanisms are designed to ensure that operational commands and data exchanges comply with stringent safety protocols, minimizing risks and preventing accidents. These systems often include redundancy and fail-safe designs to ensure continuous functionality, even under challenging conditions.
As cyber threats to rail and transport networks grow, cybersecurity has become a top priority. Advanced gateways and embedded computers act as secure nodes within the network, implementing encryption, access control, and anomaly detection to protect against unauthorized access and cyberattacks. These systems are built to be highly resilient, ensuring that communication across the transport network remains secure and uninterrupted.
Examples of our Products in Action
duagon interface cards, rugged panel PCs, and embedded single-board computers or main systems for train servers are integral to various railway applications, including control, monitoring, information dissemination, and entertainment systems.
Here are a few examples of how our products are used in various applications:
For the connection to the train consist network (MVB, HDLC, IPTCom, TRDP, CIP, PROFINET), leading door manufacturers rely on duagon interface cards. The communication interface encapsulates all functionality to exchange real-time process data, reducing the load on the control unit. Additionally, the interface module incorporates advanced security features to harden the control units and thus, making the network more secure.
A secure Ethernet gateway with an integrated software firewall can act as application-layer gateway (ALG), separating the onboard operational (TCMS) network from the multimedia network. The ALG allows for real-time data to be exchanged in an efficient manner and ensuring Quality of Service. Additionally, multimedia streams are routed at a high throughput to share video and audio feeds across the networks.
The onboard multimedia and telematics system covers four categories of services, including video surveillance (CCTV), passenginer oriented services such as the passenger information system (PIS), driver and crew oriented services like seat reservation system and operator oriented services like condition-based maintenance. All of these services can be deployed on individual onboard computing systems or centralized on a single high-performance computing system.
HVAC units, comprising refrigeration equipment, heat exchangers, boilers, and other functions, require precise integration through digital and analog input/output channels to deliver optimal cooling or heating for passengers. Our PC3 programmable modular I/O controller simplifies temperature management across individual vehicles or entire trains, offering a tailored solution (Hardware and Application Software) that meets customer specifications.
