V/Line is developing technical and performance requirements for all crossing work, including dual gauge. This will include:
- Minimum Wheel/rail cover requirements;
- Performance requirements for fixed spreaders and gauge retention mechanisms;
- Performance requirements for flange back guarding/checking mechanisms; and
- Desirable and absolute limits for design gauge.
- These will be issued to projects and external suppliers prior to receiving designs or type approval applications for review.
The ATSB is satisfied that the actions proposed by V/Line will, when implemented, adequately address this safety issue.
