Athearn Santa Fe Super Chief HO Passenger Train

After putting away the American Flyer I got my Athearn HO passenger train out of the basement. Took about an hour of digging.
It is an 8 unit train with an F7A and F7B locomotives. The B units had no crew cap and added to the streamline look of the train.
The cars in include a baggage car, coach, observation dome car, dining car, Pullman coach, and observation can in the rear with a pointed end to wrap up the streamlined look of the train.
These are from the 1970s.
