scope:

This specification applies to all continuously welded rail track whether:

• designed and installed as such (including any subsequent re-railing) or
• converted from jointed track by either in-situ welding of the existing rails or re-railing, in both cases using existing sleepers and ballast.

Purpose

This specification defines the requirements for the design, installation and maintenance of continuous welded rail (CWR) track (for the purposes of this specification "design" means "configuration"). It also specifies the methods to be used when stressing CWR in plain line and switches and crossings.
