Project Profile: Hitachi Caravaggio (Rock) Double-Deck EMU, Italy

The Hitachi Caravaggio, branded as ‘Rock’ by Trenitalia, is a high-capacity double-deck Electric Multiple Unit (EMU) developed to modernize and increase capacity on Italy’s core regional railway networks. This project profile details the technical specifications, operational parameters, and strategic impact of this advanced rolling stock deployment.

Technical Specifications

The Caravaggio EMU is engineered for high-density regional services, featuring a lightweight aluminum alloy carbody to reduce axle load and minimize energy consumption. Its distributed traction system, with engines placed along the trainset, eliminates the need for a dedicated locomotive, thereby maximizing internal space for passengers. This configuration allows for an acceleration rate exceeding 1 m/s², crucial for frequent stop-start operations on regional lines. The train operates under a 3 kV DC power supply, with a maximum traction power output of 3,400 kW.

Signaling and safety systems are anchored by the integration of the European Railway Traffic Management System/European Train Control System (ERTMS/ETCS) Level 2, enabling higher operational speeds and increased line capacity with enhanced safety margins. Onboard systems include a smart surveillance network with anomaly detection, side and front-facing cameras for improved driver awareness, and a high-performance HVAC system that dynamically adjusts based on passenger load. The interior is designed for accessibility, featuring wide gangways, ergonomic seating, and dedicated spaces for passengers with reduced mobility.

Key Takeaways

• Enhanced Network Capacity: The double-deck configuration directly addresses capacity constraints on Italy’s most congested regional corridors, significantly increasing passenger throughput without requiring major infrastructure modifications.
• Technological Modernization: The deployment of ERTMS/ETCS-equipped rolling stock is a critical step in standardizing and upgrading Italy’s national rail network, improving safety, and enabling more efficient traffic management.
• Improved Energy Efficiency & Passenger Experience: The use of lightweight materials, intelligent climate control, and a distributed traction system contributes to a lower environmental footprint and reduced operational costs, while amenities like Wi-Fi and USB charging ports elevate passenger service standards.
