Railway trackbed design
WebDesign of concrete trackbed for S-Type track. I'm currently working with the design of a railway trackbed for 160T axle load, and the client specifically intends to use the S-Type track based from Railway Technical Institute design and methodology from Japan. Any guidelines, reference and sample calculation will be highly appreciated. http://www.nurailcenter.org/tech-and-pub/doc/briefs/NURail-UKY%20Research%20Brief%20Kentrack.docx
