If you run the trains thru the top floors of the skyscrapers, people will be able to walk down the stairs to their office. Nice!
Of course, you'd have to build the skyscrapers to support all of that extra weight, not to mention the structural torque when only one train stopped at any given moment.

Unsurprisingly, he had a career in publishing, not architecture.
Q/ Any other futuristic postcards out there?
