978-1-78466-285-1 (ISBN)
There is a continuing need to update the use of advanced systems, promoting their general awareness throughout the management, design, manufacture and operation of railways and other emerging passenger, freight and transit systems. By emphasising the use of computer systems in advanced railway engineering, this book contributes to this goal.
These research studies will be of interest to all those involved in the development of railways, including managers, consultants, railway engineers, designers of advanced train control systems and computer specialists.
