That’s something I was wondering too! In Cities in Motion they only took one of the two lines and that wasn’t good at all, since a lot of time in cities you have two lines with different endings covering a common, very used area. Well, in CiM you had like 100 angry people waiting for line 1 and line 2 buses just passing by, completely empty.
A more useful example in train fever would be:
City A—-\
———— City C ——-> City D
City B—-/
Passengers willing to go to City D from City C should take the first passing train, no matter if it comes from City A or City B. Does it work like that?
