Another question to ponder is why Lionel has been reluctant to offer any follow-up white tank cars to add to the set? I believe only one single add on car has ever been offered, though it seems certain that a 3 car add-on set would be a great seller.

There is a chance I am mistaken, but I believe there were 2 add-on cars to this set. (don't have the catalog numbers handy)
For years I have been dreading (from a wallet point of view) there would be a catalog that fills in the entire 12 or 13 missing road numbers between the last intermediate car and the end car for this set all in one fell swoop. So far, my fears are not materializing, and I'm starting to think they will never make another car to match these. I'd probably be less surprised to see a new full set with Legacy in the engine at this point.
