| Gravity Train | ||
| An underground railway system that utilizes gravity for acceleration. |
This same idea is a major plot 'device' in the 2012 version of the Total Recall movie.
| They joined the line for the gravity train to Archimedes. The four of them boarded, the car was sealed, and Lilo's weight dropped away as the car fell down the inclined tunnel for almost four hundred kilometers. Somewhere under the Appenines the tunnel begain to slope up again, gradually slowing their speed to a crawl as the car nosed into the elevator which took them up to inhabited levels. |

This idea was also used in Hugo Gernsback's 1911 novel Ralph 124c 41 + - see the entry for Sub-Atlantic Tube.
And what is the best shape or curve for this tunnel to follow? See the discussion in the article for gravity-assisted subway from Larry Niven's 1976 story A World Out of Time.
