Hey! Do you mean in props/minecraft_and_rails.png?
I don’t see any transparent pixel in the tile 2/7 amd 3/7. You mean the doors with the rails right?

Hey, that's the file, but it's the part with all the rail corners. I've circled the pixels which are missing, coloured the BG Pink so they stand out. If you join a corner with a straight, there's a missing pixel of track.
I coloured these two pixels in the lightest shade, and the rails looked correct and connected.
