In railroad engineering, curve resistance is the additional rolling resistance a train must overcome when traveling on a curved section of track. Since curves are usually banked by superelevation, there will exist some speed at which there will be no sideways force on the train and where curve resistance is minimum. At higher or lower speeds, curve resistance may be a few (or several) times greater.

Famous quotes containing the words curve and/or resistance:
“And out again I curve and flow
To join the brimming river,
For men may come and men may go,
But I go on forever.”
