Releasing Jointed Rail reskins?

I recently did a few reskins of some jointed rail freeware using the reskin packs. What I would like to know is what is the sharing policy with them? If I would it would of course be free but I don't want to send anyone something and then find out I could get in big trouble for it. I have already had one person ask about the metra and I said I was not sure. The thread in question can be found here: https://forums.auran.com/trainz/showthread.php?137871-My-Two-First-Reskins&p=1587951#post1587951
If someone could help me out with an answer that would be great

Is it possible to change the title to sharing jointed rail reskins? I can't seem to find the way to.

Yeah, just edit your first post. It'll have the thread title bar in there for you to edit.

that doesn't show for me for somereason

You can't edit the title, sadly.

If it's truly important that you do that, contact the moderators and one will fix it for you.

Thanks it is now done...

Got a PM to answer my questions.
