OptiFuel is committed to rail for the long haul.

Locomotives have a 30+ year life and the most stringent performance demands of all industrial equipment. Trains haul as many as 150 cars long distances and up steep terrain — making both torque and horsepower paramount. Equipment that can meet these performance requirements is both rare and coveted.

OptiFuel partnered with Cummins and BAE Systems to create an integrated power system that provides railroads access to some of the most advanced and reliable technology in the world with the assurance of long-term support, scalable manufacturing, and an affordable price.

Modular Design

OptiFuel’s novel modularity makes customization, future transitions, and on-rail maintenance possible.

OptiFuel RNG Locomotive with Modular Power

Performance

Advanced power system achieves higher torque rating and posit range than traditional diesel powertrains, managing engine, generator, and battery power for optimal performance.

Reliability

Multi-engine engineering keeps locomotives running even with an engine down.

Flexibility

Pods can be added, removed, replaced or reconfigured, offering the versatility to change fuel types or make horsepower & torque adjustments for differing needs over the locomotive’s 30+ year life.

Affordability

OptiFuel’s novel modular engineering and world-class manufacturing partnerships provide customers unrefuted reliability and performance at an affordable price.
