PURPOSE

This specification defines the methods to be used when weld repairs to plain rail and switch and crossing components are carried out. It also specifies the permissible limits of defect and damage to be removed, including sidewear for specific rail steel types. Procedures for track-circuit deposits (zig-zag deposits) are also included.
