For context, I got word that the Golden Swoosh was coming North on a stack from Ft. Worth to Seattle through the Joint Line. I was told a T4 was leading but not what number. I heard a K3LA off of a GEVO, (i could tell because of different air pressures than a D9, SD40. etc,) I didn't know that the K3 I heard was off of the leader of the stack, and to make things worse, I didn't get a clear view of the engines to confirm the power. I then saw the power going past the railcam several miles north of me and with a football game to play in in 2 hours, I unfortunately took the L and went home.
