Here's the video from the day. Seemed to be a late decision to run with the double header today. It's also the first time I can remember seeing 463 as the road engine, usually she's the helper. No idea what the issue was that caused the delay, though you could hear them dump the air 3 different times. All ended up well, and a nice departure today.
