Railway applications. Track. Switches and crossings - Requirements for geometric design subscription-only Why should you use BS1 Scope This part of this European Standard covers the following subjects: geometric design principles for wheel guidance; definition of basic limits of supply; applied forces and their adequate support; tolerance levels. These are illustrated herein by application to a turnout. The main switch and crossing components are represented in turnouts and the principles used in turnouts apply equally to more complex layouts.
