For route alignment, the use of hump-profiles (down-up) design when feasible allows energy requirements for braking and accelerating to be reduced by slowing trains when entering the station on an upgrade and accelerating trains when departing on a downgrade. As for the optimal distance between stations, to maintain the average speed at 34 kph, and 80 kph as the maximum speed, as well as considering accessibility and convenience for the general public, the distance between stations in downtown areas should range from 800 to 1,000 meters, and in suburbs from 1,000 to 2,000 meters.
