We used to take the Texas Special from Dennison Texas to St. Louis Missouri each summer, 1950 to 1954 , and slept the cars with the fold down beds....Really neat at night to wTch our the window...We were on sidings allowing freight trains to pass by us. What were the sleeping cars called, berths? Either way it was an individual room, sort of like in the movie “Silver Streak”. It was a lot of fun. Great Thread...
