Short explanation

You have the right
- to use and copy this artwork however and wherever you want
- to study all files in sources/ (.dat, .png, .xcf, whatever)
- to edit this artwork however you want (including its sources)
- to redistribute all parts of this artwork and its sources,
  including your changes,

but you have to keep those freedoms untouched when redistributing.
Just adding the two first paragraphs to the redistribution should do
the job.

Especially, but not exclusively: By including this artwork (or parts
of it) into any other pakset(s) of Simutrans and republishing that
pakset, you should include the sources of the objects you used from
this pakset and a corresponding hint to the license, similar to this
text.

As a minimum you have to add a pointer to
- a permanently public accessible URL with the sources
- a link to http://www.gnu.org/licenses/gpl-3.0.html

I will happily include more artwork into this package, if .dat and
.png are available and the author/artist agrees in publishing under
GPLv3.

Kudos to all of the programmer and artists, who developed Simutrans.
This artwork is basing on their good work.

Hints, critic and improvements are always welcome. 
Have fun with this artwork and enjoy your freedom!
