Abstract :
The introduction of transmission systems based on the synchronous digital hierarchy (SDH) has created new opportunities for flexible and resilient transmission networks. This paper looks at reasons to deploy SDH in railway networks, and reviews some of the design considerations. The complementary technologies of WDM, ATM and flexible multiplexers are also introduced. Some of the new services which will become available once broadband capacity can be provisioned from the network to stations, control centres and the railway lineside are described
