Arnold - glad you started this up again, as a "tank a holic" I have added a few new ones to my collection since we posted last June. Here are my additions:
The Menards "Tide" tanker - just purchased from Menards, great price and great car by the way.
The Lionel 26120 KCS "1129" 3 dome from 2000
The Lionel 29629 AEC "Radioactive Material Transport" car from 2009 (still glowing )
Finally the Lionel 6-17899 NASA modern tanker. This car was the 1992 LCCA convention car.
Well those are my new buys...always hunting by the way " one dome at a time"...
Best wishes
Don
