Railway networks depend on telecoms.  Without adequate systems in place, trains would not be able to run. GSM-R, adopted in most European countries following International Union of Railways (UIC) guidelines, provides a vital radio communication link between train drivers and signallers, as well as supporting the European Train Control System (ETCS), which details train movements without the need for lineside signalling. Internet Protocol (IP) technologies are used widely in support of signalling activities, critical communication links, surveillance and CCTV monitoring amongst many others, supported by an extensive fibre and copper network. Wi-Fi provides connectivity to the internet for passengers but...

The Wray Castle GSM-R Engineering Overview is a unique course tailored to those involved in railway networks and GSM-R. GSM-R is the railway enhanced version of GSM - the Global System for Mobile communications. Originally a European initiative promoted by the International Union of Railways (UIC) to provide seamless pan-European radio communications for railway traffic traversing international borders. The UIC collaborated with ETSI (European Telecommunications Standards Institute) to specify a system that has now been adopted worldwide. The Wray Castle course introduces the work of the UIC and ETSI in developing a standards based technology specifically for railway operators. It introduces the...
