Westermo solutions for the Transport sector Solutions for the Trackside Applications Trackside applications need data communication networks with an extremely high availability. As well as mechanical robustness the products must be resilient, secure and capable of supporting legacy protocols. WeOS, the operating system used in our managed trackside products, has been developed by Westermo to ensure reliability and also provide a future proof solution. Resilient MicroLok II interlocking solution In WeOS we have a comprehensive Microlok II gateway solution that can handle up to 64 addresses....

Westermo solutions for the Transport sector Ethernet as a replacement for SDH In railway signalling, two different migrations take place at the same time. Apart from the migration from legacyIP systems, Ethernet systems now also have the capability to replace large parts of existing SDH systems (Synchronous Digital Hierarchy). In case of an increased density of trackside equipment, no additional SDH nodes are needed since Industrial Ethernet equipment is able to offer the needed availability, using either layer 2 redundancy and/or layer 3 dynamic routing. Whichever need you have, from...

Westermo Robust Connecting Mission Crit Different switches for different demands Ethernet switches for trackside use have different demands, Lynx is the most compact switch on the market while Redfox offers different combinations of FX or TX solutions. In case IP 65 or M12 connector this is supplied by the Viper family of switches. Approvals All trackside products are 3:rd party type tested according to EN-50121-4 and IEC62236-46 to withstand emission and immunity of the signaling and telecommunications apparatus on railway applications. 6

Network solutions tical Infrastructure Systems Solutions for legacy applications Legacy solution can be solved with verity communication solutions. We offer serial connectivity using PSTN modems, fibre optical modems, GSM, Device Servers, Serial adaptors, Ethernet Extenders or Switches. Long distance Ethernet on copper cables Westermo Ethernet extender technology based on SHDSL makes it possible to reuse many types of pre-existing copper cables which can lead to considerable financial savings when installing new systems. www.westermo.com

EN 50121-4 and IEC 62236-4, track side approval To fully comply with EN50121-4 and IEC 62236-4 a product must be designed to meet a series a demanding standards covering EMC, vibration and power. Track side installations needs to be more resistant to ESD, EFT, Surge, Radio frequency magnetic field as well as Puls and Power magnetic ield. The following comparison shows the difference between the test levels. ESD Radio frequency magnetic field EFT (fast transient) Surge Signal L-E Signal L-L     AC Pow.L-E     AC Pow.L-L     DC Pow.L-E     DC Pow.L-L Power magnetic field Puls magnetic field...
