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 Systems 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 on the switches. 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 on board trains.
