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.
