Westermo
Trackside and On-Board Data Communication Systems

Westermo has many years’ experience in data communication technologies for railway applications, both trackside and on-board rolling stock. Our real expertise is in developing products that can function in the harshest environments and meet the toughest approval specifications.
The company is familiar with mission-critical applications in many industries and has therefore developed products and techniques that meet the many specific needs of the rail industry. The patented Westermo FRNT protocol allows for the fastest ring-recovery in Ethernet networks: 20ms for a ring with 200 switches.
Trackside Ethernet extenders
Our Wolverine range of trackside Ethernet extenders is developed around a technology that allows the creation of Ethernet networks on old copper cables that can stretch for tens of kilometres along the trackside. Westermo is experienced in developing products to meet industry standards and we also have a particular focus on rail applications.
Trackside Ethernet switches, rail switches and modems
The critical standard for trackside systems is EN-50121-4 electromagnetic compatibility: emission and immunity of the signalling and telecommunications apparatus for railway applications.
Westermo’s trackside products, including Lynx Ethernet switches, Wolverine Ethernet extenders, Viper rail switches, and TD-23 and TD-36 modems, all meet this standard.
On-board rail switches
EN 50155 is a special on-board standard for electronic equipment that encompasses not just EMC requirements but also shock, vibration extended temperature range and humidity. The Westermo Viper series of on-board rail switches meets this standard.
High-quality trackside and on-board data communication systems
Westermo strives for the highest quality. To this end, we will endeavour to supply products, goods and services in a courteous fashion that reflects our commitment to our quality policy. Accordingly, we:
- Understand each individual customer’s requirements and needs as well as relevant regulations, so as to develop, manufacture and offer the right products
- Give our customers excellent support throughout the entire business process
- Keep up our never-ending commitment for even better quality and effectiveness
This gives and will continue to give us stability, long-term growth and profitability.
Technical support for trackside and on-board data communication systems
Westermo has always believed in providing the best technical service possible to help you, our customer, get your systems operational. All our subsidiaries employ significant technical support departments that allow us to give free of charge telephone technical support in a number of languages during normal office hours.
We also commit many hours to working with other product vendors to produce product application notes that can be downloaded from the Internet at any time.
