This won't happen. Maglev is a technology that's actually feasible and fast, and has been under research and testing since the 70s. Chuo Shinkansen between Tokyo and Nagoya is currently under construction and they're basically tunneling in a straight line through all the mountains. This is what everyone should be doing instead of unproven Hyperloop tech.

The Hyperloop idea is over a century old and has never been viable yet, and never will be until construction and energy costs drop by magnitudes. It definitely isn't feasible in any place where a regular railway doesn't already work.
