SUPERIMPOSITION OF HORIZONTAL CURVES ON VERTICAL CURVES

The rate of change in grade as recommended by Wellington is no longer applicable to modern rolling stock with low train resistance. Neither are long vertical curves needed since it is more economical to use train brakes to prevent the crowding of cars when descending. When high speeds and vertical curves are present, an increase in the equilibrium superelevation to a maximum of 12 percent is recommended.
