Wow, nobody has posted in here in a really long time. I hope it's ok if I reply here.
Anyway, I made some models a few weeks back for a map, that I'm not going to finish.
But since I like how they turned out, I thought I should post them here:
The left one (rail01) might be good for exteriors with a gravely ground underneath.
The right one (rail02) should be used with a concrete ground, like inside a train shop or depot.
Both are sized, so that the standart HL2 trains should fit on them.
