What is the primary purpose of UIC 451-1?

UIC 451-1 standardizes the electronic messages used for international rail freight, allowing different railways to share consignment and train data digitally.

How does UIC 451-1 relate to TAF TSI?

UIC 451-1 provides the technical specifications (XML/EDIFACT) that satisfy the requirements of the European TAF TSI regulation for freight telematics.

What is the Common Interface (CI)?

The Common Interface is a standardized software node defined by the UIC and TAF TSI that allows railways to securely exchange standardized messages.

UIC Leaflet 451-1: Standardized Data Exchange for International Freight

UIC Leaflet 451-1 establishes the standardized messages for the electronic exchange of freight traffic data. It is the technical bridge for international consignment and train monitoring.

What is UIC Leaflet 451-1?

UIC Leaflet 451-1 is a core digital standard titled “Electronic data interchange (EDI) – Message standard for freight traffic.” It provides the technical specifications for the electronic messages used between Railway Undertakings (RUs) and Infrastructure Managers (IMs) to manage freight shipments.

In the context of Interoperability, this leaflet ensures that a digital file sent from a railway in Poland can be read and processed by a computer system in Germany or Turkey. It defines the structure of the data for the two most critical documents in rail logistics: the Consignment Note (CIM) and the Train Composition message.

Functional Scope and Messages

UIC 451-1 covers several message types that facilitate “paperless” rail freight. Each message has a specific role in the logistical chain:

Consignment Note Message: Contains all commercial and legal data about the cargo, sender, and recipient.
Train Composition Message: A technical manifest listing every wagon in the train, its weight, length, braking characteristics, and any dangerous goods (RID) data.
Train Running Forecast: Provides the IM with estimated times of arrival (ETA) at border points or handover stations.
Wagon Release/Receipt: Messages that confirm when a wagon has been handed over to another carrier.

Technical Architecture and Formats

Historically, UIC 451-1 was based on the EDIFACT standard. However, in alignment with modern IT trends and TAF TSI (Telematics Applications for Freight), the leaflet has transitioned toward XML Messaging.

The standard also defines the Common Interface (CI)—a specialized software node that acts as a secure “post office” for these messages, ensuring that data is encrypted and delivered reliably across different national networks.

Alignment with TAF TSI

Within the European Union, UIC 451-1 serves as the practical implementation guide for the TAF TSI regulations. While the TSI provides the legal mandate for digital cooperation, the UIC Leaflet provides the actual “coding” instructions and data fields that developers need to build compliant software.

Comparison: Manual Processing vs. UIC 451-1 Digital Flow

Process	Traditional Manual Handling	UIC 451-1 Digital Interchange
Border Crossing	Paper documents must be handed over; 1-2 hour delay.	Data arrives before the train; near-instant handover.
Data Accuracy	High risk of transcription errors.	Single-source data; highly accurate.
Dangerous Goods	Manual verification of RID documents.	Automated alerts and instant safety manifest.
Fleet Management	Wagon tracking via phone/fax.	Real-time GPS-linked status updates.
