Specialists in SD70 Variants 

Refined. Reinforced. Reborn.

Full-Spectrum CustomizationTailored to Your Mission. Engineered for Precision.

C.O.R.E. has become Europe’s foremost authority in the development, customization, and restoration of SD70-series locomotives. Originally built for North American freight, the SD70’s proven reliability and raw power make it a perfect platform for modern adaptation—and no one does it better than us.

SD70: Reinvented by C.O.R.E.

From the classic SD70M to the SD70ACe, we build and upgrade these locomotives to exceed European operational standards. Every variant produced in our facilities is re-engineered with enhanced cooling systems, upgraded traction control, and emissions systems compliant with EU regulations. Our internal designation system allows clients to choose from baseline freight haulers to heavy-duty, dual-fuel hybrid models.

What Sets Our SD70 Program Apart:

• Custom Modularity: Clients can select power packages, cabin tech, bogie configurations, and even regional signaling compatibility.

• Hybrid & Eco Refits: We offer cutting-edge hybrid electric or dual-fuel conversions for SD70s, reducing environmental impact without compromising haul capacity.

• Heavy-Duty Retrofits: Reinforced frame options and overhauled drivetrains make our SD70 variants suitable for some of the toughest freight environments across Europe and beyond.

• Full Lifecycle Support: From initial build to ongoing maintenance, we service every SD70 model that leaves our line—or returns to it.
