My questions as a kid in the 50s:
My dad gave me his old pre-war Lionel 1684 steam engine set and I want to know why it makes such an O-zone smell, and why does it often derail on the old Marx manual switch tracks? Haha
I still have his set. It doesn't run well but I display the engine and tender alongside a Lionel passenger station on my "modern" 1950s small diesel layout as many old steamers are preserved in real life.
