The letter B represents our downtown and the letter E represents a principal recreational area. My engineers suggest a light rail system where each train has three cars and can carry 50 people in the comfort they are accustomed to. They have designed the system so it takes 15 minutes to traverse a leg from one station to its neighbor. Each train station will have room for two trains, but there will be only one track between stations. The engineers say that there is no justification for more tracks.
Several trains can go on the same track provided they are going in the same direction.
Little Hasan, on the other hand, wants every passenger to get to his or her destination without changing trains and by one of the shortest paths possible. Further, he wants to be sure that even at times of peak demand, passengers can get to their destinations quickly. Liane and Ecco began working immediately. After several minutes, they presented a schedule and train routing to the Sultan in which the latest passenger arrived at his or her destination after 105 minutes. The Sultan nodded.
