What is ATTI?

The ATTI SG is a UIC special group within the Freight Forum. It is made up of RUs, some of which are UIC members and some of which are not. It works on an independent basis, with only the General Assembly determining its remit.The ATTI SG sets the rules governing the transfer of wagons between participating RUs;
these are based on the GCU (General Contract of Use for Wagons). In order to facilitate
international freight transport, the participating RUs undertake to comply with the current
internal regulations, including appendices. The objective of the ATTI SG is to enhance
cooperation between RUs, harmonising and developing the relevant rules accordingly. It
aims to allow better forward planning as well as to increase the quality and safety of trains
subject to the agreement (ATTI trains).

The ATTI SG has an extranet portal hosted by UIC where all essential information,
documents and QMS data can be stored and accessed.

The ATTI SG has an executive committee. Within this committee, selected specialists from participating RUs work on further developments to the “Agreement concerning the Technical
Transfer Inspection upon the exchange of wagons” and on the implementation of
the quality management system.

Improved forward-planning for trains

The procedure for the inclusion of trains in the agreement can be simplified. No need for “random sampling” acceptance inspection as per GCU Appendix 9, point 5 (since partner RUsʼ quality indicators are known to be sufficiently good). This means that the transfer inspection at the handover location, which is performed under the “random sampling” procedure, can also be dispensed with.

Reduction of costs due to “random sampling” inspection no longer taking place; train not held up at handover location, no additional staffing costs for the execution of the transfer inspection.
