In STEAM I an currently still working on my coaster project (which I will be on for a while). Anyways, as I worked on my project, I was stumped. I wanted to connect two two-way-tracks, but when I tried to intercept them, the tracks wouldn't math up. I thought I was doomed, as my aspect of our collaboration would not work. Then my idea hit. It was quite a bright idea, but I had not yet thought of the shapes. Here's why: My idea was to cut a normal track in two, and connect one of the halves on each side of the intercepting two-sided-tracks. The problem was, my two sided tracks went sideways, and the normal track was completely direct. So, the idea was trashed. I knew I was on the right track, but my initial idea needed to be tweaked.
I decided to ask Mr. Aringo. His advice was to keep my original layout, but instead, change the "straight track" idea to curved tracks, so that they would come in and fit into the double connectors. I am currently working on building the curved tracks. So, I guess I would say that I was so close to the key thought. I was right on track, but not there yet. And unlike before, I didn't give up, but kept thinking!!
