My uneducated guess:
Looks to be normal progression to me.
I believe pulled from industry is their term for "exit stage left" for your car.
I believe they must ship out of the south end. You went from north to south.
It also looks like they pulled your car for the rail car.
I am in the same shipping set up, "Adv. Ship Notice to Dest. Ramp"
I was D1 on 11/20 with est. delivery 12/18.
The system sure seems like it is rolling fast.
