?? newbie asking about curving smoke trail ??

Diomede

Is there a tutorial or similar on how to do a curving smoke trail for a train on curving railroad tracks or a jet that is banking in the sky?

If it's for something like on your thumbnail image I would try a torus with a volumetric mat.

I don't remember a tutorial. You could use Metaballs and use a volumetric material.

I made sky writing for a plane with a symlat

Thanks for the suggestions.  For the moment, I've decided to use a banner.  I was going to do a smoke trail similar to Chhole's.
