SOLVED. endlessly railroad building SF [s]

[Mariab]

It is a SF book. I read it 35 years ago. I think was published in the 50-60´s.
For some reason a community has to build endlessly a railroad (to survive?). The main character is a male.
That is all I can remember.
Can U help me?

Does everyone else except me know what CF is?

[Lostshadows]

No clue either. Maybe Christian Fiction?

Could be Inverted World, published in 1974.

The city is winched along tracks through a devastated land full of hostile tribes. Rails must be freshly laid ahead of the city and carefully removed in its wake. Rivers and mountains present nearly insurmountable challenges to the ingenuity of the city’s engineers. But if the city does not move, it will fall farther and farther behind the “optimum” into the crushing gravitational field that has transformed life on Earth. The only alternative to progress is death.

Has a male protagonist.

You're welcome...ironically that's one of the only 4-5 SF books I've read in my entire life...as you can see, I didn't even recognize it until CF was changed to SF.
