DB Cargo Completes Rapid Rollout of LEADER System Across Diesel Fleet

DB Cargo has completed the rollout of the LEADER (Locomotive Engineer Assist Display & Event Recorder) driving assistance system across its entire Class 77 diesel locomotive fleet. Since the end of March 2026, all 60 locomotives have been equipped with the technology, marking a significant step toward improving efficiency and sustainability in rail freight transport.

Faster Deployment Through Pragmatic Execution
The installation was completed within just four months, driven by close coordination between development, production, and on-site implementation teams. Instead of routing locomotives through workshops, installation teams fitted the system directly on parked units along operational routes, minimizing downtime.

At peak efficiency, up to 25 locomotives were equipped within two days, supported by maintenance depots in Nuremberg and Oberhausen.

Real-Time Support for Energy-Efficient Driving
The LEADER system provides train drivers with real-time recommendations for optimizing driving behavior. By analyzing route data, train position, and operational conditions, the system calculates efficient driving profiles that help reduce unnecessary energy consumption.

This digital support enhances operational transparency while enabling more consistent and efficient train handling.




Proven Technology Extended to Diesel Operations
LEADER has been in use at DB Cargo since 2016, primarily in electric traction. Its successful adaptation to diesel locomotives demonstrates its flexibility and scalability across different fleet types.

Testing confirmed that the system performs reliably in diesel operation, enabling DB Cargo to extend energy optimization benefits across a broader portion of its fleet.

Measurable Efficiency Gains
The rollout is expected to reduce fuel consumption by approximately 4–5%, contributing to lower emissions and more resource-efficient operations. This aligns with broader industry efforts to improve sustainability in rail freight without requiring major infrastructure changes.
