You can see a demo of this road here: (https://www.youtube.com/watch?v=NLltQPlejvU&t=4138s)
This is a fictional 1-track catenary I made for my fictional high-speed train. There are solar panels mounted above that are not the primary source of power, but provide supplementary power throughout the day in order to reduce power consumption.
This update fixed how the wires bend around curves, which was unprototypical originally.
I also made the wires thicker, so they're more visible. Earlier, they were so thin, the game would barely draw them and they were barely visible.
If you want to reskin or edit it, I've included the .fbx file, which can be imported in Blender 2.8.
