Here's a breakdown:
* Diesel Engine Power: The power output of a diesel locomotive engine varies widely depending on the model and size. Common ranges are from 1,000 to 6,000 horsepower.
* Traction Motor Power: The power output of the electric motors (which drive the wheels) is usually less than the diesel engine power. This is because some power is lost in the conversion process.
* Tractive Effort: This is the force the locomotive can exert on the rails to move the train. It's measured in pounds of force.
Example:
A typical freight locomotive might have a diesel engine producing 4,000 horsepower, but its electric motors may only output 3,000 horsepower. This would translate to a tractive effort of around 70,000 pounds.
Important points:
* Diesel locomotives are not power plants, so they don't generate electricity for the grid.
* The power output of a diesel locomotive is not constant. It varies depending on the speed and load of the train.
* Modern diesel locomotives are highly efficient, converting around 40% of the fuel energy into useful mechanical energy.
It's more accurate to talk about a diesel locomotive's power output rather than power generation.
