to be fair, i havent unlocked substations yet so perhaps their utility will show themselves then, but as youve made small electric poles the primary method of electricity distribution, medium electric poles are essentially ONLY used to bridge between big and small electric poles, with literally no other purpose, which is kind of tedious.

honestly id just like to know why you did it like this

I will attempt to elaborate a little. As you are constructing, be it a bus or city blocks, there comes a point where your electric poles will come near poles of a separate electric network. The game engine attempts to connect all poles, making a single electric network. Transmission poles, combined with the wiring rules, work to limit the cross connect of your separate electric networks. Think of the overhaul as a quality of life tool, for constructing and maintaining separate electric networks.

Edit: I touch on this in the FAQ along with other information that you might find helpful.

okay, i thought about it a bit more and i can see why this would be more useful in tight spaces. thank you for clarifying.
