Thanks Guys for the information. I decided to just stick with the Black tank car/White print version of the Gatx Tank Cars that I already had. So I ordered the single car from some time ago and two pack from this catalog. That will give me six cars. I will just have to wait out more cars or buy some more two packs. I guess nobody would figure it with the train moving.
Does anybody know the date of these cars being used (real life) The last photo from Pops above?
Thanks Joe
