· To build models of railway system performance, material properties for soils and ballasts are traditionally obtained by carrying out tests on representative volumes, e.g. triaxial testing []. As ballasts have relatively large grain sizes, triaxial equipment has to be able to accommodate large diameter samples of 300 mm or more.
