Subgrade Infrastructure :: Trackopedia

The role of the subgrade in railways is similar to that of a building foundation. The applied loads are transferred by the deflection of the rail to the ballast bed and then passed on via the subgrade to the subsoil. The effects of a subsoil that cannot carry much load are devastating. Back in the 19th century it was recognized that the proper drainage of water and the adequate dimensioning of

Modulus of Subgrade reaction Which one to use

subgrade reaction is for short-term loadings to be used for loads such as lift-truck wheel loads. These loads only affect the first few feet of the soil and have little, if any, long-term consolidation settlements. The second subgrade reaction is for long-term loadings to be used for loads such as wide area rack or uniform storage loads.
