[0.18.7] Non-optimal train pathing

[dahhakd]

Hi.

I'm experiencing an issue where the train chooses a much worse path, like 2 to 3 times longer than the shortest.

Here in the first image you can see where I am, where I want to go and the long path that is being chosen:

Here you can see that there is a path from where I am, because it is chosen up until that point on the tracks:

Then if I go just a little further on the right path, even with automatic routing, then the rest is calculated correctly:

Here is another instance on the same map, but the difference is not as dramatic:

Thanks!

Train stop "Defense 5" adds penalty that makes your longer path be in fact "better" (has lower cost). Short path is when there is no other path that could avoid train stop "Defense 5"

When the path includes a train stop that is not the destination -> Add a penalty of 2000.

Oh, I see. Thank you for the clarification and sorry for the bother!
