Last week (20-23 September), we participated in the exhibition Innontrans 2016. For those who could not attend, have the opportunity to take advantage of our new products and solutions on our website.
New range of Ethernet switches that manage increasing demand for high-speed communication networks on-board rail vehicles.
Westermo has introduced a new generation of Ethernet train switches that provide highly robust networks to support many end devices and high data rates. Specifically designed for train applications.

New range of Ethernet switches manage increasing demand for high-speed communication networks on-board rail vehicles
To meet the growing need for more capacity in train communications networks, Westermo has introduced a new generation of Ethernet train switches that provide highly robust networks to support many end devices and high data rates. Specifically designed for train applications, the wide range of interoperable Viper switches delivers reliable and versatile solutions for train networks, enabling optimal configuration for every need.
Based on the previous well proven and highly popular train switches from Westermo, the new models provide a range of 12 and 20 ports standard Ethernet, Gigabit Ethernet and PoE (Power over Ethernet) variants as well as additional routing functionality to enable the connection of subnets and improved overall network performance.
The Viper is available with up to 5 gigabit ports to meet the need for connectivity of gigabit end devices, such as WLAN access points and network video recorders. Simultaneously, lightning fast failover on gigabit ring ports can be achieved.
The Viper offers eight PoE ports that support the IEEE 802.3af/at plug-and-play PoE communications standard. PoE enables both power and data to be transmitted on a single multi-core cable, especially useful for camera applications, reducing overall wiring and enabling faster installation. The Viper with PoE is available in variants for low or high voltage power supply range allowing installation in any rail vehicle regardless of power standard. The Viper can also provide gigabit speed over the PoE ports, making the switch ideal e.g. for WLAN access points.
Specifically designed to provide highly robust networks and long term field operation, the Viper range has been tested and approved to exceed the EN 50155 on-board railway standard for electronic equipment, as well as an extended range of approvals with NFPA 130 (NA fire & smoke) and shunting radio EMC requirements from European rail authorities.
The Viper has been designed to be very compact and ultra-thin, enabling installation within the confined spaces of railcar panels. The M12 connectors are integrated into the housing to reduce size and further protect against vibration. With an ultra-robust design, sealed to IP67 and vibration resistant to military standards, these units are ideal for situations where mechanical stress, moisture, condensation; dirt or continuous vibrations could adversely affect the function of standard Ethernet switches. A GORE-TEX(R) membrane is used to prevent condensation build up by normal climatic day/night cycling.
As well as high levels of reliability, the switches offer unique functionality that simplifies the creation, installation and maintenance of networks. The Viper switches’ WeOS operating system provides an extensive suite of IP networking features and protocols allowing resilient and flexible networks to be created.
WeOS is also able to balance data traffic on the network to maintain maximum throughput and stability. The introduction of increased traffic from new cameras or video streams will therefore not affect the stability of the network. In the event of any link or hardware failure Westermo’s unique FRNT technology is able to re-configure a large network in 20ms.
For easy configuration, the Ethernet switches can be safely accessed from anywhere in the network using the WeConfig network configuration tool, or directly via a console port on switch.
The use of IP technology has become the standard, over the last few years, for creating the data communication backbone used by the Train Control Management Systems (TCMS), Passenger Information Systems (PIS) and Infotainment on trains. Robust Ethernet switches featuring a range of IP networking protocols are being used to build these networks which now are absolutely critical to the operation of the train.
As more and more different types of equipment are connected to these networks the need for more ports and capacity is created. More equipment also means that more cables need to be installed both power and data. PoE (Power over Ethernet) technology is the ideal solution to this issue where end devices can be powered through the network cable resulting in significant cost and space savings.
Westermo can provide an extensive range of network devices that can be used to create reliable solutions for many different applications such as WLAN access points, observation and surveillance cameras, multimedia displays, network video recorders, online timetable information, diagnostic data and much more. The very compact Viper series of Ethernet train switches provides up to 20 ports with or without PoE and up to 5 gigabit ports. The versatility of the Viper series and the ability to process high amounts of data traffic solves the growing need for network capacity.
Westermo has also developed solutions to challenges that are specific to the train market. Train inauguration is a process where the network can automatically reconfigure as carriages are joined or rearranged. The TTDP (Train Topology Discovery Protocol) in the RedFox Rail backbone router allows this reconfiguration meaning that networking skills do not have to be taught the operations staff of the train operating company.
In some applications it is not possible to use network cables, for example to get information off the moving train to the ground, connecting carriages where a specialized train coupler is not available for network cables or to provide internet access for personnel and passengers. Westermo can provide a range of wireless products that can meet these needs.
Westermo switches and routers are powered by WeOS (Westermo Operating System) which provides an extensive suite of IP networking standards allowing reliable and secure networks to be created. With Ethernet connections being used for many train subsystems from the actual TCMS to PIS and Infotainment systems, there are risks that data congestion could occur if mistakes are made in connection or configuration. WeOS provides fast reconfiguration in the event of network failure and firewall functionality that can be used to block all but the required data from certain sections of the network. VLANs (Virtual Local Area Networks) can also be used to segregate networks, and prioritisation of data can guarantee delivery of critical packets on time.
Come and see - the Next Generation Network Solutions for the Rail industry
Westermo would like to invite you to visit us at the upcoming InnoTrans exhibition in Berlin from 20th-23rd September 2016. We will be located in Hall 4.1 booth 321 where you will be able to meet us and see the next generation network solutions for the rail industry.
Westermo provides a full range of data communications solutions for both trains and at the trackside. Great knowledge and understanding of this marketplace drives our product designs to be true to specification and capable of operating reliably over a long service life within rail environments. To ensure the highest quality, all Westermo products are manufactured in our own state of the art industrial electronics manufacturing facility in Sweden.
We feel that the best way for you to understand the quality and robustness of our solutions is for you to see and touch the actual products. As well as this you will get a chance to meet some of our communications experts who have been involved in data communications solutions for the rail industry going back over many years.
