Thanks to everyone who particpated in the Fourth Survey. The results were compiled from over a hundred votes for Lionel's 6464 Postwar Boxcars.
The first-place winner was ahead of the competition from the beginning of the voting. Results for the runner-ups were close behind. The submissions were made February through May 2006.
Thanks go to the TCA for letting us use pictures of 6464 boxcars from their excellent article during the survey. (The photos below are adapted from online auction images.)
