I'm just starting to design my first rail system(LHD), and I've encountered some issues while trying to design an intersection.
First, I couldn't figure out how to make a curve without first attaching to an existing rail which is problematic since nothing in the BP designer can connect with anything outside of it. I got around that by making a BP of just a single curve (after deleting the connecting piece).
The bug where the designer's bounding box doesn't visually match was easy to work around once I figured out what was happening. Hopefully the finished blueprint isn't cut off.
Apparently signals can't be placed on the ends of tracks. Being unable to attach more rails to these curves inside of the designer means that I have nowhere that the game will allow me to place signals.
Is there a way to make a more complete BP for intersections, or will they be mostly manual each time?
Edit: realized after I posted that the left and bottom curves are going to the wrong side. Glad I noticed before trying to use it.
A dual-level system did cross my mind, but the real drawback is that you'd have to remember which level is going e. g. north/east and south/west and place each signal on the correct side or rotate the blueprint the correct direction. Every. Time. Forgetting once will result in a signal being on the wrong side leaving no path for the trains to travel. I would forget frequently.
