Railway applications - Track - Switches and crossings for Vignole rails (series; anchored on Part 2 - requirements for geometric design)

Scope

Multi-part CEN series defining requirements for switches and crossings used with Vignole (flat-bottom) rails, spanning definitions, geometric design, wheel-rail interaction, actuation/locking, expansion devices and layouts. This entry anchors on Part 2, which sets wheel/rail contact geometry and crossing-nose dimensioning rules used by infrastructure managers and turnout manufacturers for design and type approval; read together with EN 13231 (acceptance of works) it governs specification and construction quality of switch layouts.
