I didn't see machinery, but there were many electrical bits and bobs there: wires, outlets, switch plates, etc. There were also hunks of wall strewn all over the structure, piled in corners and heaped together in mounds. I would have loved to come across old equipment in there!
I found an abandoned electrical factory recently (well, I knew it was there, I just explored it) and although I couldn't get inside, it was really interesting. It had Ivy growing up the sides and a garage door with big enough dents for me to stick a camera under.
It really is. Ivy is like, you know how if you stay at a job long enough you get promoted? It's like God saying "You rock because you were here for so long, now have some cool wall-climbing leaves." My friend's house has ivy on it and I'm so jealous. I wish there was ivy climbing up my house. *3*
The ones taken under the garage door, not well. Nothing came up, just blackness. So I turned on the flash and got either a branch or some kind of plant growing out of the asphalt in there, but it was out of focus and still mostly black. I think next time I go, I need to take a flash light and not be so afraid Slenderman will come out from under that garage door and kill me.
