Portland Streetcar and TriMet MAX should be split on the one-way couplets through/around downtown because the A and B Loop lines are separate lines... which means an eastbound and a westbound file for the Blue and Red Lines (which will need to be extended out to Hillsboro Airport at the end of the month), and a north and south file for the Yellow, Green, and Orange lines. If A and B weren't separate lines, I think the current setup would work, but as it is, station pairs are offset from each other along Morrison/Yamhill and 5th/6th.
Likewise, the 10th/11th Ave couplets should be split, which will affect the N/S Streetcar Line.
