Abstract

Mass Transit systems are making increased use of technology to bring more information to the desk of the Operators. System performance is therefore directly impacted by the large amount of data being managed by the system both coming to the operators from various sensors or subsystems, and command and control information going in the opposite direction. In order to achieve optimum performance, the system architecture must be adapted to accommodate this increased level of information and associated data traffic. The Jubilee Line Extension Mainline Control System in London is a good representation of a railway control system that has to handle the increased information flow. This paper presents an overview of the architectural and design changes that were introduced in the Jubilee Line Extension control system to handle the challenge of increased data. The goal o
