Seamless real-time control systems: challenges for the railway industry

Since the explosive growth of computing technology in real time computer control systems during the 1970s, system integration has always required special attention. With the advent of networking technologies, system integration has become so complex that it often requires unique customised solutions, and despite the technological advances, system integration still remains a challenging problem to be resolved. The article explores the subject of applying system integration to the mass transit railway industry. Also included is an analysis of the problem from a process and technology viewpoint, and a look at the emerging technologies that promise to simplify system integration. A case study on a new system interfacing approach that is being followed in the design of Hong Kong´s new West Rail line by Kowloon-Canton Railway Corporation is also described.
