Looks like they hit and stopped but were told they could not back up to keep going?

The manufacturer will likely total the entire shipment. LKQ Corp will probably end up with them.

I get that happening with a truck, but how do you screw up a train load out not knowing the low bridge on the route?

This reminds me of what I saw in the late 70's while driving truck near Elizabeth NJ. There was a long line of the old style , as in open top, auto transport cars. As far as I could see every auto on the top level had it's roof torn off. It was a time in railroading where the 3 level rail cars were not yet in wide use like they are now and there were a lot of low clearance bridges on main limes. I would assume that in both these cases a dispatcher is most likely on an unscheduled vacation, if not out of work altogether.
