1- Background
1.1 - A country's DIUM contains the UIC codes and names of the stations open to international freight
traffic and the distances between these stations and the border points of neighbouring countries used
to calculate tariffs. The UIC codes for these stations must be entered on the CIM consignment note/
CUV wagon note in order to identify the stations of departure and of destination.
A country's DIUM also contains the UIC codes and names of the handover/unloading points used by
the railways and the codes of associated freight terminals. The UIC codes of these locations are to be
entered on the CIM consignment note/CUV wagon note in order to identify the place of handover/
unloading.
The distances between stations are used to calculate the transport tax for all international freight
convoys, to the extent that the corresponding international commercial conditions are governed by the
DIUM.
Each handover/unloading point is attached to a freight terminal. The distances defined for a terminal
serving a handover/unloading point are also used as the distances for the handover/unloading point
itself.
The DIUM also includes the list of ITU terminals (see List of abbreviations - page 21) and other
appendices concerning technical and/or commercial information.
Additional information concerning terminals and handover/unloading points is communicated in the
form of specific references.
1.2 ~ The DIUM is an important document for international freight transport operations. The distances,
terminals and handover/unloading points are presented using a uniform structure for easier editing
and management. Tables of kilometric distances enable the price of international freight transport to
be calculated.
1.3 - Each RU assumes responsibility for the accuracy of its own data.
Where several RUs are authorised to operate international freight transport services in the same
country, one of these RUs must take responsibility for publishing the DIUM data of the country
concerned and sending it to UIC. If the RUs cannot come to an agreement, the UIC DIUM/
Management Group NHM shall act as a mediator. The responsible RU shall ensure that the necessary
data, where provided by other RUs, corresponds to the determined formats and is delivered within the
agreed deadlines (see List of abbreviations - page 21).
