• Economic aspects of ballast projection 
• Comparison of methods in France and Spain for rolling stock 
• Infrastructure assessment methods 
• Review of available literature 
• Next steps and recommendations regarding standardization and research. 

Who is PD CEN/TR 14067‑7 for? 

PD CEN/TR 14067‑7 on railway applications is useful for: 

• Railway engineers 
• Train ballast manufacturers and suppliers 
• Manufacturers of railway rolling stock 

Why should you use PD CEN/TR 14067‑ 7?  

Railway-induced ballast is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. 

PD CEN/TR 14067‑ 7 provides the general aspects of ballast projection and state of the art and gives a summary of studies and incidents by various countries manufacturers and also gives information regarding specific cost estimation for the homologation of trains regarding ballast projection. 

Overall, PD CEN/TR 14067‑ 7 provides test procedures for train ballast projection to determine suitability to serve as a common state of the art to facilitate design and investigations in the railway sector providing a supportive platform to transfer train loads to the ground.
