I received my first Lionel set on Christmas morning. The train was operating on Super "O" Track on a a loop around the Christmas tree. Obviously, I was beyond excited! That began a hobby that has continued "interrupted" to the present day. As with many of us, my hobby was "interrupted" by the usual suspects: high school, dating, etc. Later, when our oldest son was about 6 years old, I set up a layout of Super "O" Track for us to enjoy, and, he has a layout currently.
During the Postwar Era, I always operated my layout on Super "O" Track. My father built o beautiful train table for me, and helped me secure the Super "O" Track to make a good size layout. We were able to find the track at a very substantial discount at a post-Christmas sale in the early 1960's, at a nearby hardware store that was closing out their train sales.
I thoroughly enjoyed my Super "O" layout, and my friends liked how realistic the track looked on the layout.
Did you operate your trains on Super "O" Track during the Postwar Era?
