UIC Leaflet 917-1: Electronic Messaging for International Freight Traffic
UIC Leaflet 917-1 establishes the standardized data structures and messaging formats for the electronic exchange of freight transport information. It serves as the technical foundation for digitalizing the Consignment Note (CIM), allowing railway undertakings to transmit cargo and routing data across international borders with high accuracy and speed.

What is UIC Leaflet 917-1?
UIC Leaflet 917-1 is a foundational standard in the realm of Information Technology for rail, titled “Electronic exchange of information for the management of international freight traffic.” Its primary objective is the transition from paper-heavy administrative processes to seamless Electronic Data Interchange (EDI).
In an era of global supply chains, the ability to transmit digital information regarding goods, weight, hazard levels, and destination is a prerequisite for Interoperability. UIC 917-1 provides the “grammar and vocabulary” for these digital messages, ensuring that an IT system in one country can perfectly interpret the data sent by another.
The Digital Consignment Note (CIM)
The most significant application of UIC 917-1 is the digitalization of the CIM Consignment Note. The leaflet defines the data fields required for:
- Goods Identification: Utilizing standardized NHM (Harmonized Goods Nomenclature) codes to identify cargo regardless of language barriers.
- Commercial Parties: Identifying the consignor, consignee, and carrier using the RICS codes defined in UIC 920-1.
- Routing and Timing: Defining the path of the shipment through specific border points and estimated arrival times.
- Customs and RID: Incorporating mandatory safety data for the carriage of dangerous goods (RID) and customs status (T1, T2, etc.).
Integration with TAF TSI
UIC 917-1 is a key enabler for the European TAF TSI (Telematics Applications for Freight). It ensures that data remains consistent as a train moves through different Infrastructure Management systems.
- Wagon Status: Messages can include specific wagon numbers and their sequence within a train, facilitating automated “train composition” reports.
- Real-time Tracking: By standardizing the “event messages” (Arrival at station, Departure, Border crossing), it allows for end-to-end Logistics Management and tracking for the end customer.
Benefits for Operational Safety and Efficiency
The implementation of UIC 917-1 messages provides:
- Elimination of Manual Entry: Reducing the risk of human error at border crossings.
- Safety Information: Instant access to RID data for emergency services in the event of an incident.
- Pre-Arrival Notification: Allowing terminals to plan Rolling Stock unloading and shunting before the train even arrives.
Comparison: Paper-Based vs. UIC 917-1 Digital Workflow
| Process Step | Traditional Paper (CIM) | Digital (UIC 917-1) |
|---|---|---|
| Data Creation | Handwritten or local print. | Standardized EDI message. |
| Border Crossing | Physical handover of documents. | Pre-arrival electronic transmission. |
| Hazard Info | Manual search in paper books. | Automated RID flag in system. |
| Customer Visibility | Delayed/Phone-based updates. | Real-time tracking integration. |
