Seamless real-time control systems - Challenges for the railway industry

Since the explosive growth of computing technology in real-time computer co ntrol systems during the 1970s, system integration has always required spec ial attention. With the advent of networking technologies, system integrati on 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. This article explores the subject of applying system integration to the mass transit railway industry. Also incl uded is an analysis of the problem from a process and technology viewpoint, and a look at the emerging technologies that promise to simplify system in tegration. 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.
