This was a series for the Lionel brand name "6464" from memory,which is pretty fuzzy on the rest of the details sorry Flash.....
Thanks, Jason. The "6464" clue and search gave a little information here. [edit] More info. It is a collector car series by Micro Trains. New information to me.
This series of Lionel copies was commissioned by a hobby shop in Portland, Oregon, in the mid-90s. They replicated key Lionel cars' paint jobs in N-scale using Micro-Trains cars. I don't remember the name of the shop but it was in an older part of town on the east side, across the river from downtown. It filled the basement of an old department store and had a fairly large layout for a local club.
