Modernization for additional years of operation

The modernization and retrofit of electrical equipment can help rail vehicles and buses achieve maximum availability and many more years of reliable operation—often spanning several decades.

KIEPE specializes in upgrading and refurbishing existing vehicles with new drive electronics, onboard networks, climate systems, or electrical equipment. Their service portfolio ranges from simple cable refurbishment to partial equipment upgrades, all the way to complete project management.

Many vehicle operators face intense cost pressure—so KIEPE has collaborated with them to develop various modernization concepts. Upgrading existing vehicles extends their lifespan, improves ride comfort, and enhances attractiveness for both drivers and passengers.

Modern drives and onboard power supplies can significantly reduce vehicle maintenance costs (delaying life cycle costs/LCC). Efficient drive technology and onboard converters can also lower vehicles’ energy consumption, reducing both CO₂ emissions and energy costs.

Modern propulsion systems pay for themselves within approximately four to eight years due to lower energy costs, depending on operating conditions and infrastructure. KIEPE has already demonstrated this in multiple successfully completed projects. They are happy to develop a tailored economic analysis for your vehicle fleet.
