Is it to prevent the toothed drive wheels from skipping?
The outer wheel turns more times than the inner as is
goes around the curve.

My son has spend his allowance on a couple of the new Thomas sets (Percy and
James). James comes with one piece of curved track (along with others
including a switch).
I’ve noticed that all the Duplo track that’s come with these sets has a
ribbed texture on the rails, with the exception of the curved track – that’s
ribbed on the outside rail, like everything else, but the inside rail is
smooth.
This has been puzzling me. Can anyone think of a reason why the inside rail
of a curve piece should be smooth rather than textured?
Thanks,

The old Lego track (12V and 4.5V) was like this too.
