Abstract :
This paper provides an overview firstly of the development of railway signalling systems, which has been a combination of engineering inventiveness coupled with reactive engineering after accidents and incidents. It then moves on to explore the technological opportunities and necessities facing railway control systems engineers. It explores too the quest for improved performance, and the need to focus not just on safety, but to contribute to the delivery of a cost-effective, efficient and environmentally friendly railway as well. Finally, the author briefly considers the skills and expertise we will need to deliver the systems of the future.
