Smallest reasonable radius curves for N scale?

[BN-6811]

Thinking about building a small coffee table N scale layout. What is the smallest radius curves for N scale you can use without causing problems? Not planning on running any large locomotives or large rolling stock.

Thanks!

You could probably go down to 9 3/4. That should run most smaller 4 axle locomotives and 40-50FT rolling stock

Not sure I would go any lower, but others may have better experience with smaller than that radius curves.

If your going to use flex track, build easements in and out of curves and it will help things operate and look much better.

Can I run 4 axle locomotives on 8 1/2" (Kato Unitrack) ?

You will need to check the minimum radius for any locomotive you want to operate and see what its stated minimum radius is.

Thanks. I just checked on the Bachmann website for my EMD GP 40 Norfolk Southern:
"Performs best on 11.25” radius curves or greater". Problem solved !

Yes, possibly with some speed reduction depending on how easily the trucks turn. Long passenger cars or "86 foot"-type long cars may derail due to too much overhang. Also, if you have parallel tracks, you will have to space them a bit farther apart to ensure clearance. 6 axle diesels will most likely derail. I do not have any steam so cannot comment.

Thanks everyone, good info.

The Bachmann Peter Witt streetcar will handle 5 1/2" curves. Running a streetcar maybe preferable on a coffee table layout.
