For the next two years I will not be able to update any of my projects including this one. Resource packs are usually compatible with future versions of the game. I do not authorize anyone during this two year period to continue or reupload my work.
This pack replaces the texture for slanted rails with a 16×22 pixel texture. This fixes the issue where the rail appears stretched or distorted. This pack should be compatible with 1.13+ but I can't guarantee it because I haven't tested it on previous versions.
Default (has none to little performance impact and highest quality): Download
Resource Pack Compatible (can decrease performance, lower quality): Download

Feel free to modify for other packs when credit is given.
