If you replace the wire with the transmission line, it just gets through it. I hope this can be fixed

You can stack them, which is intended. Also don't see transmission lines as pure replacement. They transport a higher voltage with higher efficiency but you have to use transformers to transform between high- and normal voltage.

Ok, but it looks pretty weird

I know, you can do strange things with it. It's like the tree under the rail.
