"Very interesting. Are any photos of the interior of such cars available on line? I'm trying to figure out what "floor tubes" look like."
Any interior photos will only show the location of the floor tubes which were capped with a brass casting fitted with a hinged cover plate.  The casting and cover plate assembly was flush with the top of the floor and sometimes barely discernible within interior photos.  The bulk of floor tube assembly was below the flooring of auto cars.   
 
Floor tubes were either round (5" OD) or oval (5" x 6" OD) and varied in length from 20" to 28".  Tubes were mounted perpendicular to the floor or at slight angles in order to clear various brake gear components, etc.  Auto cars equipped with Evans Auto~Loaders could be fitted with as few as eight or as many as sixteen floor tubes depending on the model of the loader.  Early NYC loaders did not utilize floor tubes while the later model did as the NYC purchased the tie down assemblies and floor tubes from Evans; the latter design was commonly referred to as the NYC "Combo" loader system.  
 
"Most of the cars listed had auto racks, some had end doors, and a few had both."
 
The percentage of auto cars equipped with end doors and loaders was historically quite small; generally less than 10% of the total.   The mechanics of  the installation of the cable hoist assembly on the "A" end (door) and the racking of the car end with doors (especially when loaded) persuaded many railroads to avoid this combination.
