EN50155 Railway

Onboard Data and Information Systems Usher in the Era of the Smart Railway

The global rail industry has long needed modernisation and system upgrades. Legacy equipment and networks strain under the pressure of increased demand for capacity, in addition to changing expectations and regulations from passengers, industry associations and governments alike. 

All these factors have led to the emergence of the smart railway system. Smart railways use the latest technologies – such as 5G, edge computing, Internet of Things (IoT), big data, cloud computing, analytics, artificial intelligence (AI), machine learning (ML) and global positioning systems (GPS) – to improve safety and quality of service. 

This technology is used to manage rail operations more efficiently by sharing data across rail infrastructure components. Today’s smart railway solutions include, but aren’t limited to:

  • Passenger information 
  • Safety and security monitoring 
  • Rail communication 
  • Real-time geolocation tracking 
  • Smart ticketing 
  • Rail and freight operations management

Sintron -EN50155 Railway computer

Sintron's EN50155 Certified / Compliant Computing and Networking Solutions

Taiwan-based Sintrones is an ISO 9001 and IRIS ISO/TS22163 certified producer of railway computers and in-vehicle computing systems. The companyrailway computers meet the rigorous EN50155 requirements for vibration, shock, input voltage range, electrical isolation and extreme temperature, humidity and EMC. This ensures its solutions provide safe and stable operation in harsh environments such as high-speed trains. 

  • Industry Certifications: EN50155, IRIS, EMARK, IEC61373
Sintron’s EN50155 certified solutions are specifically designed for railway rolling stock applications that guarantee reliable performance, endure extreme temperature, and withstand severe shock and vibration in train control and railway applications.

  • An Operating Temperature Range of -40℃ to 70℃ – in Fanless Conditions 

Sintron EN50155 railway computers (fanless box PC) are designed to meet the railway stringent environment with wide-temperature capabilities ranging from -40℃ to 70℃ while functioning under full CPU load. Its uncompromising performance and extraordinary reliability is ideal for Railway system applications.

  • Vibration and Shock Protection

Robust and reliable M12 connectors are used to enhance system stability and protection, and feature fast-locking housing to resist high-shock and vibration loads. This enables the onboard railway computer series to withstand vibration of up to 2.5GRMS and shock of up to 15G. 

  • Isolated Power Input Design Meets Class S2 Interruption Requirements
Sintron onboard railway computer offers a wide input range of 24~110VDC power input with isolation, which covers almost all railway application requirements. In addition, its power surge protection and reverse polarity voltage protection prevents system damage if the input voltage is ever accidentally reversed.

  • 5G/LTE, GPS and Wi-Fi Functionality – an All-in-One Communications Solution
To ensure the safety of passengers and staff, railway operators require a reliable communication solution. In response to their needs, Sintron onboard railway computer has been developed to support 5G/LTE wireless, GPS and Wi-Fi functionality.
