Hyperloop is envisioned to run in 100Pa of pressure. According to the Wikipedia page on vacuum, that is considered "medium vacuum." It's also quite close to the region where offgassing and vapor pressure is going to be a major component of the ambient pressure, which is where you start needing complex vacuum pumps.
