What if you could get more from the locomotives you already own?
Your locomotives represent significant invested capital. Rivotto's Nx25 is designed to help you get more from those assets—improving fuel efficiency and reducing emissions without waiting for the next generation of locomotives.
Explore the opportunity ↓Your fleet is working hard.
Your capital should work harder too.
Railroads face competing priorities: controlling fuel costs, improving operating efficiency, maintaining reliable service and meeting emissions commitments—all while investing in the next generation of rail transportation.
Fuel costs
Reduce one of your largest controllable operating expenses.
Existing assets
Unlock more value from locomotives already in service.
Emissions
Make measurable progress toward environmental commitments.
Capital priorities
Free up financial capacity for fleet renewal and emerging technologies.
More energy. Less fuel. Same locomotives.
Nx25 is Rivotto's proprietary supplemental fuel technology, designed to improve energy performance during combustion. It offers railroads a potential pathway to greater fuel efficiency and lower emissions while continuing to operate their existing diesel locomotive fleets.
Illustrative performance targets, not guaranteed results. Actual performance depends on locomotive type, duty cycle and operating conditions.
What could better fuel efficiency mean for your railroad?
Adjust the assumptions to estimate annual gross savings for a hypothetical railroad.
Move the sliders to explore scenarios. These are estimates, not performance guarantees.
Important: Illustrative estimates of gross savings before Rivotto’s shared savings model. Actual customer savings will depend on verified performance and the agreed sharing arrangement. Estimates exclude implementation costs. CO₂ estimates use approximately 10.21 kg per U.S. gallon of diesel avoided and exclude any separately verified emissions effects.
Improve today's fleet. Invest in tomorrow's.
Better fuel efficiency does more than reduce operating expenses. It can create financial flexibility to support the railroad's longer-term priorities.
Existing diesel fleet
Improve fuel efficiency with Nx25
Lower operating costs
Create recurring savings and reduce fuel-related emissions
Measured performance. Real locomotives.
Lower fuel consumption per gross ton-mile
Reported in a four-locomotive EMD test compared with baseline. Rivotto's rail testing provides a foundation for further demonstrations with railroad operators.
Customer-specific trials can evaluate fuel use, locomotive performance and emissions under representative operating conditions, with results normalized for train weight, route, weather and duty cycle.
What could Nx25 deliver for your railroad?
Start with a locomotive. Measure the results. Evaluate the opportunity across your fleet.
Rivotto works with railroad operators to identify suitable demonstration assets, establish performance baselines and assess the potential for fuel savings and emissions reductions.
