This version has 58 teeth and the other one has 56.
Does anybody have the actual part to verify the number of teeth?

I took some digital photographs of several actual parts and counted the teeth on the images (which is easier than counting the teeth on an actual part).
All 6 parts I've checked have 55 teeth.
So both versions are wrong, unless there have been different moulds with different amount of teeth.

additionally:
"old" should be removed from part name.
(Each part at some point in time will become "old".)

I believe that only one version should stay.
Also Bricklink has only one version 'wheel1a' (http://www.bricklink.com/catalogList.asp?q=train%20wheel)

x447.dat (this file) should stay. IMHO.

You may want to consider breaking this up into subparts with either 5 or 11 teeth.

I think this file is good to go now.
Further improvement always is possible,
but it sat here for years now.

I especially checked the origin which matches
the official train wheel parts well.
