This leaflet sets out the technical conditions which must be met so that roller units basically designed
for conveyance on road vehicles may also be carried without difficulty by rail.
The roller units described in this leaflet can only be transported by rail on special wagons.
As a general rule, there is no obligation on railways to undertake transhipment. Any exception to this
rule shall be subject to specific agreements with railways in which the specific rules applicable under
particular conditions shall be clearly defined.
The rules laid out in this document mainly cover permissible dimensions, securing devices on wagons,
the strength of the roller units and their identification markings.
Containers and roller units already covered by UIC Leaflets 592-2 to 592-4 (see Bibliography .-
page 28) do not fall within the scope of this leaflet.
