"The immediate problem with our meat brains is that they have no back-up. We can lose the most precious information we have from one bump on the head or stroke. You want a mind system with back-up that can access other databases."

| Underground MagLev Train | ||
| Magnetic levitation train that travels through a tunnel; a vacuum reduces drag. |
| The train sat rigid as a steel bar, poised in midair above its magnetic monorail track, disgorging passengers into Dallas Station. Its fifteen cars had borne their passengers in quiet efficiency from New York to Dallas in just over half an hour, cradled in magnetic fields, traveling through vacuum at close to orbital velocity, deep underground. |

Depending on the depth of the tunnel, the train might also take advantage of a more direct route, as well as the accelerative force of gravity.
