ATTI – Handover Quality Management

Home

A common agreement defining rules for the transfer of interoperable wagons and freight trains between railway undertakings in international rail freight operations.

About ATTI

What is ATTI?

ATTI stands for Agreement on Freight Train Transfer Inspection. This agreement defines the rules for transferring interoperable freight trains and wagons between participating railway undertakings (RUs), based on the GCU (General Contract of Use for Wagons). To facilitate international freight operations, participating RUs commit to complying with the agreement.

ATTI is managed by the ATTI Study Group, a UIC special group within the Freight Forum. The list of ATTI member railway undertakings is available for download on the UIC ATTI page.

ATTI Functions

Quality Database

ATTI includes a central Quality Management System (QMS), where all quality indicators are collected in the ATTI Quality Database. Both the database and the web-based ATTI QMS application have been developed and are operated by RailData, upon request of the ATTI Study Group.

The tool provides IT support for:

Planning interoperable freight trains and wagons

Calculating required sample sizes for technical inspections

Uploading inspection plans and results

Consolidating and calculating quality indicators

Documenting and reporting irregularities

The Quality Database also offers insights on:

Technical handover inspections

Train and wagon data

Exceptional consignments

Dangerous goods handling

How It Works

The core principle of ATTI is that participating RUs evaluate each other’s handover quality and share findings

Each year, RUs enter their estimated number of wagons on international trains, categorized by destination and transit RUs. Based on this data, the QMS calculates how many wagons each RU should inspect and spreads the inspections evenly over the year.

RUs then carry out random quality checks and enter or upload results to the ATTI Quality Database by the end of the following month.

The system consolidates the data and generates daily reports, always showing the current year. Each RU can access automated reports for its own operations, including summaries and detailed evaluations. In addition to daily reports, annual and year-end summaries are available.

Inspection plans and results can be entered manually via the ATTI QMS web interface or uploaded in CSV format via the web or FTP.
