Maybe not every minute, but in Japan, the same track can handle a new bullet train every few minutes, like clockwork. The throughput is enormous. And the footprint of a track is much, much smaller than a single runway, so it's not uncommon for even modest rail stations to have 15+ tracks. Chicago O'Hare has the most runways of any airport in the US, at 8, and they aren't all usable at the same time, since they intersect, and wind direction varies. And that's an enormous facility.
