Of course, this is infinitely more feasible than Musk's hyperloop because a) it's a real fucking train, and b) China is the world leader in HSR. This thing loops sexy.

You don't actually need to hold a perfect vacuum, you could get massive drag reduction by just reducing the atmospheric pressure by some amount. Just regular having a massive metal tube sitting at 0 psi with a high speed object traveling through it is like building a multiple mile long bomb. Sitting at 12 or 10 psi would still give a speed boost, but rapid depressurizing wouldn't be as catastrophic. You could also do that with a lot less infrastructure
