The Powhatan Arrow was initiated in 1946, with NO baggage cars. Coaches, diner, & observation car - all pulled by a Class J 4-8-4. Sometime in 1956, the Powhatan Arrow got baggage cars as other trains were discontinued and the Powhatan Arrow picked up their work. So, I doubt if the baggage cars every got the Powhatan Arrow lettering like the original cars, and most of the baggage cars were older HW cars.
