Yes, that's a loud K5HL, even though it may sound like a K5LLA.
A BNSF SD70ACe and GEVO lead a loaded Scherer coal train bound for Georgia onto the Fort Scott Sub as an empty coal passes north in the background. Ironically, trailing unit BNSF 6318 now has a K5LLA as of 2020, though he still has a K5HL in this video.
And apparently the audio of the first blast is used in a Roblox game called A&G, which 11 people have told me about now.
Filmed at Santa Fe Junction in Kansas City, MO.
