Thinking it was just a breakdown, no vehicles nearby and it looked to be in good shape otherwise. Didn't see smoke or anything major, so hopefully it was just a hose or something that could quickly be fixed anywhere other than the side of the interstate.
Sadly I saw a white 80 series getting loaded up onto a tow truck around 1145 west bound near the I-10 & Avondale(?), if you're a CSCer I hope you get it all figured out!
