Railway applications. Track. Switches and crossings - Requirements for wheel/rail interaction Ingestion-build-115288 appropriate connection between duct and1 Scope This part of this European Standard specifies: characterisation of wheel and track dimensions; geometric design principles for wheel guidance; design principles for wheel load transfer; deciding whether movable crossings are needed. These are illustrated by their application to turnout components: switches; crossings; check rails. but the principles apply equally to more complex layouts.
