"I had a little surprise from BNSF last night, as I caught what I believe to be the king of Nathan airhorns, the K5HLB. I got some nice distance audio at the start, but I wish I would've gotten the first blast I heard of it, because it was one of the most ominous airhorn sounds I've ever heard. Train arrives at 2:40.
