If the wheel was rolling, and I'm sure it was, the she had plenty of steam for the whistle and calliope. Both items use very little steam in the grand scheme of things, and when underway the AQ's boiler is always carrying a full head of steam, which I know is over 300 psi. I don't remember the exact operating pressure of the AQ's boilers, but it is up there far above the DQ or Belle of Louisville's because it must be regulated down before it gets to the main engines.
