Funny that trains came up. I have the complete set my folks gave me for Christmas in 1959. It's O gauge Lionel with the Super O track. I probably have 3 or 4 miles of O gauge track now but its pretty much worthless. Most of it is the regular 3 rail as super O became hard to find here for a long time.
My Dad and I added stuff all the time from yard sales and flea markets for years. 
I've had appraisals over the last 15 years or so and the prices keep falling, now it just sits in boxes in a closet.
None of my kids, (6), or grandkids, I forget, have any interest.
I'm sure they will all have a laugh when they find out I've bought slot car stuff.
