Railway Technical Web Pages Infopaper No. 7 Railway Stations – Design and Operation By P Connor 1 and F Schmid 2 One of a series of articles prepared for the RTWP website. Introduction Airport, harbours and stations form interfaces within modes and between multiple modes, providing both intermodal and intramodal connectivity. However, a more in depth analysis reveals that such facilities have functions that go beyond their role of links in a transport chain. The authors discuss some of the issues that arise from the need to satisfy a multitude of requirements, focusing on passenger transport. This paper was developed on the basis of a presentation made to the delegates attending the Intelligent City Forum held in Birmingham on 26 May 2011, sponsored by Rail Champions. A Beacon for the Area Stations in city environments, with other major structures in close proximity and often surrounded by large, visually and commercially attractive corporate buildings, have to stand out as beacons for the community and the city. They must be eye-catching, built to high standards and they must attract passengers to the railway. Good examples are Berlin Hauptbahnhof in Germany, Lille Europe in France, Liège-Guillemins in Belgium (Figure 1), Bejing South Station in China and the future Canary Wharf station of Crossrail and the renovated St. Pancras in London.
