DESCRIPTION
The city is winched along its tracks through a devastated world. Rails must be laid ahead of it and removed in its wake. If the city does not move, it will fall behind the 'optimum' and into a crushing gravitational field. The alternative to progress is death. The rulers of the city make sure its inhabitants know nothing of this. But the dwindling population is growing restive. And the rulers know that the city is falling further and further behind.
