Five cars came off the rails. Most or all of them were carrying fracking sand. No one was hurt, no major traffic problems over it. http://ktul.com/news/local/streets-blocked-after-train-derails-in-downtown-tulsa
You're probably not alone. The train had just come off the Southeast Kansas & Oklahoma (old Santa Fe) interchange. The cars could easily have come off that rough rail, and not fallen over until they hit the switch.
Do they? I should have searched their site more thoroughly. They use a couple of miles of the BNSF--the old Frisco--as a bridge in downtown. Literally, as that's how they get across the Arkansas River. I get the feeling they had better learn how to keep their cars on the tracks, or the BNSF is going to balk at that arrangement!
They certainly have an interesting collection of short lines. Their SKO map shows the line southwest out of Tulsa, which goes to Muskogee, as a BNSF line. Surely the UP didn't sell that portion of the Katy to them. Last time I was by that yard in Broken Arrow, it was Yellow Peril all around!
