Train Fuel Consumption Calculator
Fuel Burn Scales With Distance, Not Time
Diesel-hauled rail services report fuel efficiency the same way road vehicles do — consumption per 100 km travelled — because it's distance, not duration, that determines how much fuel a locomotive burns. This calculator converts a consumption rate and trip distance into total fuel required, and optionally into a total fuel cost.
The Formula
Total Fuel = (Distance × Consumption Rate per 100 km) / 100
When a fuel price is supplied, total cost is simply total fuel multiplied by the price per liter.
Where This Is Useful
- Route cost estimation — project the fuel cost of a diesel-hauled service across a given route before committing to a schedule.
- Comparing consist configurations — test how consumption changes with different locomotive types or train lengths by varying the consumption rate input.
- Budgeting against fuel price volatility — re-run the same distance and consumption figures against different fuel prices to see the budget impact of a price change.
Worked Example
A 300 km run at a consumption rate of 4.5 liters per 100 km, with fuel priced at $1.50 per liter:
| Distance | Consumption rate | Total fuel | Fuel price | Total cost |
|---|---|---|---|---|
| 300 km | 4.5 L/100km | 13.5 L | $1.50/L | $20.25 |
How to Use This Calculator
- Enter the Distance to be travelled, in kilometers.
- Enter the Fuel Consumption Rate in liters per 100 km.
- Optionally enter a Fuel Price per Liter to also get a total cost.
- Select Calculate to see total fuel required and, if a price was given, total fuel cost.
Related Calculations
Pair fuel cost with the Rail Fare Calculator to compare operating cost against revenue on the same route, or check Gradient Resistance to see how much of that fuel is spent fighting an uphill grade.
