Just thought I'd share a nifty blueprint book for railways. The original work isn't mine but I increased the spacing between the inter-rail big power poles to the maximum defined by Krastorio 2 (a prefect 32.25 blocks = 1 chunk).
The blueprint are rotationally symetric and you can turn a curve into a junction without having to remove anything. Added a 2-to-1 T-Junction too.
P.S. I don't know if this is the right place to share this, but factorio prints website doesn't work for me and didn't really know where to post this otherwise.
