"Interesting data. The SP began piggyback in May of 1953 and by the
mid-1950s, was acclaimed by _Trains_ magazine as the "piggyback champ" due to its
traffic volume.

For a whole lot more on this topic, I really recommend David DeBoer's book,
_Piggyback and Containers_ from Golden West Books.

But as we all now realize, it took a PENNSYLVANIA RAILROAD President to pull
the pieces together and make the whole thing make common sense nationwide
by starting TRAILER TRAIN Corporation. That was 50 years ago.
