Still a thing

 Hyperloop transportation was proposed by Elon Musk as a new form of transportation in 2012. He didn't want to do it himself (create a company to make it a reality) but others did take the idea and started creating it "from the ground up." Progress is slow, but hyperloop is still a thing.

Multiple layers of government have to be onboard to make this new concept happen. They want assurance of safety, economic viability, cooperation from their voter bases, etc. 

It's so appealing: to move passengers or cargo between big cities safely at near-air-speed, with no carbon emissions or exhaust, nearly noise-free, and at affordable cost. (Go to label "Hyperloop" for background.) Pods move through near-vacuum tubes using magnetic levitation.

A new study in the U.S. evaluates the feasibility of building a hyperloop to link Chicago-Columbus-Pittsburgh.
