I just looked at it; https://www.youtube.com/watch?v=JpRFspwxepI -> They should move that middle station; by placing it just above the passing point, the vehicles now have to stop twice, of which one time in the middle of nowhere (while the other vehicle is at the middle station).
If they move the middle station by just a small distance, they can have it at the passing point, and both vehicles can be there at the same time, eliminating pointless stops
Or are they actually planning a second middle station, and just haven't gotten around to building the platform yet? The trains already stop there (at 9:20 in the video)
