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:
“In philosophical inquiry, the human spirit, imitating the movement of the stars, must follow a curve which brings it back to its point of departure. To conclude is to close a circle.”
—Charles Baudelaire (1821–1867)
“Hence to fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy’s resistance without fighting.”
