oa Civil Engineering = Siviele Ingenieurswese - Axle load and track deflection on a heavy haul line
In the 21st century, the use of railways has grown to make them the preferred choice for the transportation of heavy freight. Thus new demands are constantly being placed on our understanding of rail track infrastructure performance. Track engineers are challenged to be more cost-effective and to base their designs on the design life of the entire track structure. It is therefore necessary to promote research that will evaluate the components that affect track foundation performance and expected service life. With the increase in annual freight demand, the need arises to increase the gross vehicle mass and, in turn, the axle load of freight wagons.
