For the signs that you typically see on these platforms, I measured the basic dimensions of the signs on the old Kibri platforms I got from eBay to invent my own. In this case, I glued a strip of flat styrene between two round styrene pipes. I gave these a coat of silver paint, and then made up some signs that look something like the real thing might.
What I can't decide on is what COLOR to make the seats! I originally wanted to go with the dark grey color shown above, but the grey is so dark they just don't look quite right. Below are some other colors I tried. I'm curious, which one do you think looks the best?
Please do let me know about your opinion of the bench colors. I'm not sure I have a favorite (I think I gave myself too many choices!).
