As a long-time fan of the Chunk-Aligned Railway System with Wires, I wanted to keep using this concept with the 2.0 rails, so I updated it. The intersections and entries/exits also got an update, which I took from here, and I also cut down the amount of power poles needed by about 50% thanks to the wire reach increase from 30->32 tiles in Patch 2.0.7.
Slapping down rails has never been easier. Each BP fits on top of each other without collisions, everything is chunk-aligned for guaranteed fits and the power poles all have red/green wires too. Also, it looks neat on the map.
