>>2027859could do dual gauge like picrel with aligned centerline. but still it would make more sense to run one of the west side jr lines into this than the tokyu line. assuming the goal is one seat rides from shibuya/shinjuku. it wouldn't make sense to spend a billion usd just to give meguru ku a one seat ride to haneda. how much demand to haneda do they expect anyway with keikyu+monorail+future jr line existing?
