Villagers can walk over rails if theres a open trapdoor in the corner

Cannot reproduce, the rails appear to prevent the villagers completely from pathfinding through the door. It's possible that they nudge each over onto the rails, but they definitely try to avoid them. They won't even be able to assign themselves to job sites on the other side of the door because the rails are like a wall to them.

I don't know what to tell you because I keep seeing it walk over the rails.

If you can reproduce this in vanilla, unmodified Minecraft with the official server software, then please provide a small video with the debug screen enabled (hit the F3 key) demonstrating the issue.

The server restarted and its no longer happening. How strange.
