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:
“The years-heired feature that can
In curve and voice and eye
Despise the human span
Of durance—that is I;
The eternal thing in man,
That heeds no call to die.”
—Thomas Hardy (1840–1928)
“It was not seen that woman’s place was in the home until she began to go out of it; the statement was a reply to an unspoken challenge, it was attempted resistance to irresistible change.”
