Your statement is true for the FEF-3 #844, but NOT for #3985, as the tender is definitely the "limiting factor" on the real 4-6-6-4 "Big Challengers".
My Challenger tenders can go around far sharper curves than their locomotives can.
Models are a whole different story than real locomotives!
C'mon, Jack,
Next you'll be telling us that the 3985 wasn't equipped with DCC and a Tsunami sound system.
