Looking for good train maps/servers

I’ve been looking about these forums and the website itself for maps and stuff for building trains in gmod, and i’ve found some stuff but not much, if anyone knows any good maps or servers that sponsor building trains please let me know.

What’s your steam? I’ll add you. I own GRW. http://steamcommunity.com/groups/garrysmodrailworks
