FS Group and Europe’s Rail Showcase GoA4 Automation Progress in Bologna

Why It Matters

The demonstration proves that fully driver‑less trains can run on current ETCS infrastructure, accelerating Europe’s push for higher‑capacity, more reliable rail services. It also showcases the tangible progress of a major Horizon Europe investment aimed at modernising the continent’s rail system.

Key Takeaways

• FS Group completed GoA4 ATO trials on ETCS line in Bologna
• Hitachi Blues tri‑mode unit demonstrated automatic, remote driving, obstacle detection
• Project R2DATO funded with €160.8 M (~$175 M) under Horizon Europe
• 77 partners aim to boost rail capacity and punctuality across Europe
• Remote driving replicates driver cab functions, enabling flexible train control

Pulse Analysis

The successful demonstration of Grade of Automation 4 (GoA4) at FS Group’s San Donato test ring marks a pivotal step toward fully driver‑less rail operations in Europe. GoA4 represents the highest level of train automation, where the system handles starting, stopping, speed regulation, and emergency braking without any onboard crew. By integrating this capability with the European Train Control System (ETCS) Level 2, the trials prove that existing signalling infrastructure can support autonomous services. This aligns with the EU’s broader strategy to modernise rail networks, reduce reliance on manual operation, and meet sustainability targets.

The February‑March trials employed a Hitachi‑manufactured Blues tri‑mode multiple‑unit supplied by Trenitalia, fitted with a complete GoA4 suite. Three core functions were showcased on the 5.7‑km ring: automatic driving that follows ETCS commands, remote driving that lets an operator control the train from a distant control centre, and sensor‑based obstacle detection that triggers emergency brakes when objects appear on the track. The test environment, equipped with 24/7 ETCS Level 2 wayside equipment, allowed engineers to validate the seamless interaction between onboard computers, trackside balises, and safety sensors, providing a repeatable approval platform for future rolling stock.

The initiative is part of the FP2‑R2DATO programme, a €160.8 million (about $175 million) Horizon Europe project coordinated by Europe’s Rail Joint Undertaking. With 77 partners—including infrastructure managers, operators, and manufacturers—the project targets 350 deliverables over 42 months to accelerate digital transformation across the continent’s railways. By proving scalable GoA4 automation, R2DATO promises to increase line capacity, improve punctuality, and lower operating costs, paving the way for broader deployment on congested corridors. Stakeholders view the Bologna showcase as a proof‑of‑concept that could reshape European rail logistics within the next decade.
