Railway applications. Track. Switches and crossings - Fixed common and obtuse crossings Ingestion-build-50790 fold and pressed joints in1 Scope The scope of this European Standard is to: establish a working terminology for fixed crossings and their constituent parts, and identify the main types; specify the different and varying ways by which crossings can be described using the following parameters: geometry of the crossing; types of construction; design criteria; manufacturing processes; tolerances and inspection.
