(From my post card collection.) L&N’s caption on the back reads: “Louisville and Nashville Railroad Diesel-powered streamlined de luxe coach-Pullman train between Cincinnati-Chicago-St. Louis and New Orleans. Smart dining car serving famous L&N meals. Full length tavern-lounge car, radio.”
Streamliner Memories 
I rode the Humming Bird from Decatur Ala. to Biloxi to visit my aunt and uncle in Pass Christian . Great memories and I always went for the ham sandwich . I was only 9 and traveled by myself. Times have certainly changed since then!
