They were running more than 8 an hour during rush before the 7000 went offline, so I'd imagine the 8000 would allow them to resume that schedule. There was a report the other day that WMATA believed the trains were overcrowded for COVID conditions and tried to get the safety commission to clear the 7000s and were denied. I see no reason why the 8000s wouldn't get them back to that earlier schedule unless there's a driver shortfall.
