I'm planning on having an outdoor train set but don't know much about it at this point . Does anyone have good and bad experiences or hits and misses that they like to share? I have set aside my side yard for it. It's 8ft by up to 70ft. Because I haven't look too much into it yet, I don't know if I will use the whole area. I also don't know what my budget will be or how much everything will cost. I plan to build it slowly of course to cut down spending too much at once. What I have in mind is to build some of the mountains, tunnels, ect myself to save cost. Share what you know .
