Sure, HSR is gonna have it worse than a minute, I was thinking of, say, subways and light commuter rail, with the 1 minute lower bound. Some of those don't spend more than about a minute not at full speed for some stations, including door-open time and de-/ac-cellerating. No train where people aren't traveling very light and prepared to get off fast is going to get quite that low a stop time, though, true.
