Railway applications - Infrastructure - Flash butt welding of rails - Part 3: Welding in association with crossing construction

Scope

This document specifies requirements for the approval of a welding process in a fixed plant, together with the requirements for subsequent welding production.
This document applies to new Vignole rails manufactured in accordance to EN 13674-1 and welded by flash butt welding to crossing components in a fixed plant, and intended for use on railway infrastructures.
This document applies to cast Manganese crossings manufactured to EN 15689, fabricated crossings manufactured from rail and crossings manufactured from forged/rolled premium steels.
NOTE EN 14587-1 is also used for the flashed butt welding of switches.
Sometimes special profiles exist in crossing construction, which are not rail profiles as defined in EN 13674 series (example: profile with machined off rail foot). In these cases, tests are defined by the railway authority in participation with the manufacturer.
