Lionel, 99 % of all my inventory is Lionel but not a certain period. There are L&N cars from a long time ago up to including the "Family Lines", the sizes are 027 and traditional and a few larger ones. Usually buy L&N when I see one and yes there 4-5 duplicates, they are run together and different loops.
My interest in L&N is based on my Grandfathers long time employment with L&N in Nashville TN. My first train ride was from Decatur AL., to Nashville TN in 1951(?) at age 6 or 7 with my brother (10-11) . My memory of the trip was it was long(130 miles +/-) .
Don't know why I wrote this, it is just a good memory of a long time ago.
