This is supposedly a 'new capital' but it's really more of a new district on the current fringes of Cairo connected by rail service that will likely take less than an hour— more to the nature of Shibuya/Shinjuku (which only became busy districts after WWII) versus the old Chuo of Tokyo as opposed to Brasilia hundreds of miles away from the old cities. And Egypt is growing fast enough that the intermediate areas will probably get built out.
