I have tried using the search feature already, but it really didn't help much. I am looking for a few specific features to put in my park.
1) rail road scenery, specifically working crossing gates; I would like to have the train stay on one level and let the peeps walk over it when it is clear.
2) Roadway scenery, things like crosswalks, directional arrows for pavement etc...

That is it for now, I may be back later if I need more help of course, thanks in advance!
