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:
“Nothing ever prepares a couple for having a baby, especially the first one. And even baby number two or three, the surprises and challenges, the cosmic curve balls, keep on coming. We can’t believe how much children change everything—the time we rise and the time we go to bed; the way we fight and the way we get along. Even when, and if, we make love.”
—Susan Lapinski (20th century)
“He made no resistance whatever, and was stabbed in the back.... I must not dwell upon the fearful repast.... Words have no power to impress the mind with the exquisite horror of their reality.”
—Edgar Allan Poe (1809–1849)
