    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 ...
