I said I'd release this back when used it in Traingrid, but now I am finally getting to it since someone asked about it. It's just an edit of the original with empty skins available, plus my green one. (no sandwiches, that's mine)

• Contents:
The model files.
VMT/VTF for green skin with "Goldstein Rail Network" logo.
VMTs for the default red/blue skins.
PNG of gray skin with no logos, for customizing.

See the readme for further info.
