Multiple choice

On curves, to counteract the effect of centrifugal force, the level of outer rail is raised above the inner rail by a certain amount. This is called

  1. track gradient

  2. track slope

  3. super elevation

  4. horizontal gradient

C Correct answer
Explanation

Super elevation is the raising of the outer rail above the inner rail on curves to counteract centrifugal force, ensuring trains remain stable and comfortable. Track gradient (option A) refers to vertical slope, track slope (option B) is not a standard term, and horizontal gradient (option D) incorrectly combines gradient direction with super elevation.
