Getting a full 1g on the moon using a circular track (or other small planets)

Yes.
However, unfortunately, little data is out there.
Does gestation and development happen successfully at 1/6G?
Or are you going to have to put the mothers and babies in this
for the first 12 years, with them only getting out 2 hours a day.
It seems likely that mature humans can probably live on a reduced
gravity planet, if they don't need to come back to earth.

Yes, this idea has been used, but my memory is too fuzzy for a clear
cite.

ISTR it involved the crew of a ship being kidnapped and put into such
a gizmo on a (our?) moon, but the idea was to convince them they were
being detained on a planet (Earth?), so that Secret Information could be
gotten out of them non-destructively. IASTR it involved Soviets and
Americans.

Best I can do; maybe it's enough to prod somebody else's memory.

I have a slightly less fuzzy memory, if it was the same thing.

They were kept on earth, in a rotating centrifuge, to fool them that
they were on the moon (or was it space) in a rotating centrifuge.
The heros eventually worked out that it wasn't due to the corrolis forces.

I've read that novel, too.

It it Endgame Enigma, by Hogan?

The title rings a bell.

I believe it's James P. Hogan's 'Endgame Enigma', which he wrote after
he stopped writing good stuff, but before he went totally Velikovsky
bat****.

I believe the idea was that they were supposed to believe they were on
a large rotating station but were actually being held ON EARTH
(assuming it's the book I recall).

Yep, Hogan's _Endgame Enigma_. Thanks everyone.

Now I'm wondering if I misremembered it so badly because it inverted
the usual apparent-gravity increase of a centrifuge. It struck me as
"unreasonable" at the time, even though he justified it perfectly. Even
Newtonian physics can be counterintuitive. ;)

Oh, and the other comment about Hogan going "Velikovsky bat****"
obviously refers to his _Cradle Of Saturn_ which assumes the
Velikovskyian idea of Jupiter being a protoplanet factory (yes, I
slogged all the way through it; best thing I can say is that it stayed
consistent). I can hardly believe there's a sequel.

Yes, but not only the sequel does he push the same ideas. If you look at the
one where everyone are using VR controls of micromachines you will find him
pushing the same ideas there too, and that is book kids might want to read!

I also gotten the impression that his books on the multiverse is something he
really believes in too, not just a story idea. Hogan used to be great, but
lately I don't know what happened to him. The worse of it all is that he
does have a full understanding of the scientific method and ocram(sp?) razor
but does not appear to be using them.

I could see an exercise room, or perhaps even a small gymnasium. But you
said "settlement". That to me means tens of thousands of people and growing
your own food etc. I just don't see all that happening in a railroad car.

It's so much easier to just build a rotating pressure vessel in orbit, which
can provide whatever level of "gravity" is desired.
