Key benefits for your organization

Compliance with current emissions regulations

By retrofitting or renewing exhaust aftertreatment systems, companies can meet stringent emissions standards such as EU Stage IIIA, IIIB, or V. This enables the sustainable operation of their fleets and reduces environmentally-related restrictions, ensuring future-proof technology.

Efficiency improvement and cost savings

Engine remanufacturing and the use of replacement engines significantly improve the energy efficiency and performance of older locomotives. This reduces operating costs through lower fuel consumption and reduced maintenance requirements.

Extension of fleet lifespan

Through targeted modifications and upgrades, older vehicles can be equipped with modern technology, significantly extending their service life and potentially delaying the need for investment in new vehicles.

Certified safety and quality

All measures taken comply with stringent railway standards and are certified according to key certifications such as EN 15085 (Welding in rail vehicle construction), UIC regulations, and other rail-specific requirements. This ensures the highest safety and compliance.

Flexible and tailored solutions

Each upgrade or modification is tailored to the customer's specific requirements. Whether for freight trains, car trains, factory railroads, or passenger trains – Zeppelin Power Systems offers solutions that are perfectly aligned with the respective application.

Sustainability through resource-saving modernization

Instead of replacing entire vehicles, retrofitting existing drive systems provides a resource-saving alternative that also reduces the fleet's CO₂ footprint.

Future-proof technology

With the latest technologies, including advanced exhaust aftertreatment and engine control systems, the vehicles are fully equipped to meet future requirements.

Comprehensive service and support

We support your company from planning through implementation to post-project follow-up, ensuring smooth integration and maximum availability.

Zeppelin Power Systems services for Rail

Cat engine upgrades for optimal performance and longevity of your locomotives

Zeppelin Power Systems offers comprehensive services for upgrades, retrofits, and modifications tailored specifically to the needs of the rail industry. With a clear focus on efficiency, sustainability, and reliability, we use state-of-the-art technologies to bring your rail vehicles up to date and ensure their long-term performance.

Engine remanufacturing with Cat engines: More power, fewer emissions

When the performance or efficiency of older drive systems no longer meets current requirements, we offer engine remanufacturing services. In this process, we replace existing drive units with state-of-the-art Cat engines that not only meet emissions standards but also set benchmarks in terms of performance, efficiency, and reliability.

Cat replacement engines: The cost-effective alternative to engine remanufacturing.

As a cost-effective alternative to engine remanufacturing, we provide replacement engines specifically designed for retrofitting existing vehicles. These engines meet or even exceed the original technical standards in key areas such as emissions performance and power.

Certified services for rail: From exhaust aftertreatment to engine remanufacturing

Renewal and retrofitting of exhaust aftertreatment systems

In response to increasingly stringent emissions regulations, we assist our customers in integrating modern exhaust aftertreatment systems. This includes Diesel Oxidation Catalysts (DOC), Diesel Particulate Filters (DPF), and Selective Catalytic Reduction (SCR). These systems meet the requirements of EU Stage V and EPA Tier 4 Final, helping to significantly reduce pollutant emissions.

Certification according to railway standards

All of our services, from exhaust aftertreatment to engine remanufacturing and the delivery of replacement engines, are certified according to strict railway standards. We meet key standards such as EN 15085 for welding technology, EN 50155 for electronic equipment in rail vehicles, and ISO/TS 22163 (IRIS standard) for quality management. These certifications ensure that our solutions meet the highest safety and quality requirements.
