Yes. :(
The NTSB made some preliminary statements earlier.
http://newsok.com/one-train-failed-to-y ... z1ysFHFEr3They are saying that one of the trains failed to take a siding. They won't say which one though (not surprising at this point). There are 3 CTC sidings--each a hair under 2 miles long by my reckoning--with electric switch machines on the Pratt sub in the OK panhandle. There's one at Goodwell, one at Optima, and one at Tyrone. They are at approximately equal distances from each other. There is another siding kind of out in the middle of nowhere almost exactly between Stratford TX, and Texhoma, OK.
Someone over at trainorders said that whats left the the WB autorack and its DPU were taken back east and tied down at Tyrone.
I think one of the stories I linked above has the eyewitness account of the long haul trucker who was pacing the eastbound Z at 68 mph after he left Goodwell, and he indicated that the train was not blowing its horn. I presume he means for level crossings, of which there are several in the immediate vicinity.
