Much of that hyperloop will need to be underground. Tunneling underground will be a monumental undertaking that will dwarf all the current underground tunnels combined to date. That is just to accomplish 1 tunnel. The amount of tunnel boring machines needed will be astonishing. The effort will require the financial support of government. When government funding is finalized, expect tunnel boring companies to grow many many times in size to take on the task. This could be a good place to invest.
