It should be noted the California bullet train is planned to run at 220mph for its fastest leg, so this is within spitting distance already.
If you pump the (vast majority of the) air out, no reason you couldn't get supersonic. That's much faster than any non-rocket-propelled train has ever gone.
The fastest train in service is around 270mph, more experimental maglevs have reached 375mph. Supersonic is 767mph, so over twice the fastest maglev.
