Behind Britain's railway modernisation lies research, design and development. Research ensures in various ways that passengers travel fast, safely and in comfort. Design and development yield new vehicles, equipment and methods; from motor-car conveyors to micro-wave communications. The electrification of the busiest mainline in the world also depends on research, design and development.
