As opposed to the first three contributors to this discussion, I truly am (aka C Weber) "an old 6464 nut"-who because of my age, should be at the end of train collecting. However my interest has not waned and so I continue to collect, trying to be more focused. I agree with J Korling regarding the differences between the true 6464 types ( including the door guides) and the most recent offerings. I forget which club I had an off-line discussion with-but it is clear that Lionel will very unlikely re-do the true 6464 type boxcars-so the offerings from NETCA, METCA, LOTS, TCA, etc. will have to do. On the other hand-some of these new cars labeled as 6464 are really nice-including the reverse color Alaskan. So I will likely continue to collect even the non-true 6464 box cars.
