This is a high-quality and well-constructed HO passenger car. Could not find a dedicated Southern Railway Post Office car, but this is a good substitute, plus providing more baggage space. And complete with interior.
The SR Bag/RPO car is great. It will work well, when properly decaled, with the train's consist. Speaking of deals, Decals were not included to identify the car beyond a car number. There should have been such words as: Baggage; United States Mail; Railway Post Office.
