Loading slit coil packs on a wagon

The running characteristics of the steel coil carrying wagons fulfil the requirements of European norms, but the lateral accelerations on the frame of the wagons come close to the limit value and may even exceed it for short periods of time. In a calculated estimate of the moment of inertia of a loaded wagon resulting from the placement of the load, it was found that it is more advantageous to put heavy coils in cradles 2 and 4 at the centre of the wagon compared to cradles 1 and 5. So that load placement would not cause unnecessary stress to the load’s bindings, the rolling stock or the tracks, the Safety Investigation Authority recommends that:

VR finds out the best placement for the coils in the wagons in order to improve the running characteristics of a loaded coil wagon and takes the results into account in the loading instructions.
