Järnvägar - Spårväxlar och -korsningar - Del 2: Geometriskt utförande
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.
