The business car was an Amfleet I, so at the time it was on average 40 years old. Looking at the report's built-in photos, "ripped" is not how I would describe that car. It was mangled at both ends and maybe 18-24 feet of the car was left in some measure of "intact".
I think I see what's going on. The two former engineers are concerned about the shell as well as the trucks, and thus wants to accelerate the replacement process. FRA is only concentrating on the parts that touch rail, the trucks. Amtrak considers it moot as it knows the whole mess and put in the replacement order, which has to go by today's standards.
