Is the caboose in a train really the lowest drag car in the chain?

Sighard Hoerner published this data in his book,' AERODYNAMIC DRAG.'
In a 'streamlined' train, if fully-boat-tailed, the tailcars investigated demonstrated as low as Cd 0.10, same as many of the railcars within the train.
Ripley and Tietgens, 1934, self-propelled WESTINGHOUSE, passenger railcar was reported at Cd 0.08.
If you go back to 1865, you'll see an example of the 'ideal' caboose.
