 The essentials of a high-speed may be set down as under :-
  1. It must eliminate lateral oscillation;
  2. It should be able to show moderate working costs;
  3. It must be reasonably cheap to construct;
  4. It must permit of reasonably simple switches;
  5. It should be capable of being built coincident with existing lines;
  6. It should be capable of being fitted to existing tunnels;
  7. It should be capable of being easily employed as a surface, underground or elevated railway;
  8. It should not concentrate the forces due to centrifugal action and wind on a single line;
  9. It should not depend for the stability of its cars upon a moving mechanism.
