Robust and Reliable: Cat Hep Engines for Demanding Traction Power Supply

Reliable power supply for trains on non-electrified tracks places high demands on the technology used. Zeppelin Power Systems provides HEP Engines (Head-End Power) that are specifically configured to meet these challenges.
Efficiency, robustness, emission compliance
A central challenge is ensuring a reliable power supply even under extreme climatic conditions, such as temperature fluctuations from -50°C to +45°C. Our Cat engines and aggregates are designed to operate stably in such challenging environments. Their robust construction and optimized efficiency help meet the high reliability demands essential for the smooth operation of a train.
Thanks to optimized exhaust aftertreatment, our traction power supply systems meet international emission standards like EU Stage V or EPA Tier 4. Combined with sound-reduced designs, they enable quiet and environmentally friendly operation in urban and protected areas.
Redundancy and emergency management
In remote regions or during long train journeys, the reliability of the power supply is crucial. Zeppelin Power Systems incorporates high redundancy in its designs, ensuring that the power supply remains operational even if a generator or engine fails.
Our solutions are designed to operate autonomously at full capacity for up to 48 hours during emergency situations, such as technical failures or challenging climatic conditions. This reduces the risk of interruptions and enhances operational safety.

Precise Detail Engineering for Maximum Cost-Effectiveness and Operational Safety in Rail Transport

Reduction of operating costs in traction power supply
Reducing life cycle costs (LCC) is a key requirement for modern train power supply systems. In addition to acquisition costs, the focus is primarily on long-term expenses for operation, maintenance, and repairs. Zeppelin Power Systems actively supports operators in optimizing these costs. Our Cat auxiliary diesel engines for rail are specifically designed to operate with maximum efficiency and reliability over extended periods.
By using advanced technologies, including optimized injection systems and modern engine management, we help minimize fuel consumption without compromising performance or reliability. Through detailed analyses of engine performance maps, we precisely determine the optimal operating point for each use case. This fine-tuning ensures that our engines always operate within the most efficient range, significantly reducing operating costs.
Technical detail engineering and innovative solutions for the highest demands
Zeppelin Power Systems offers tailored solutions that meet even the most demanding operating conditions. A key element of our system development is the detailed engineering process, where all components, from the engine control unit to sensitive components, are tested for electromagnetic compatibility. This ensures that operational disturbances are avoided.
Additionally, we conduct comprehensive fire safety tests and specify detailed cable specifications to ensure the operational safety and efficiency of the entire system. These and other measures are crucial for ensuring the reliability and safety of our systems, especially under extreme climatic and operational conditions. With our extensive technical expertise, we guarantee robust performance and maximum operational safety, even in challenging applications.
