BS EN 13232-2:2023

This document:

• establishes the design process for switches and crossings (S&C), and the use of the other parts of this standard;

• specifies the geometric design principles for wheel guidance;

• establishes the basic limits of supply;

• establishes the applied forces and their adequate support;

• specifies 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.
