When I was 12 I had the 1991 Lionel Catalog Book 2.
I was obsessed with pages 28 & 29 - the scale PRR S-2. I had never seen a locomotive that big. Four smoke stacks! So many wheels! My locomotive knowledge was lacking, but it sparked me to pick up a book.
Well, 32 years later I was able to get an upgraded version of that locomotive - the TMCC PRR S-2. It came from the same seller of my recently acquired T1 (if you are on here - thank you!).
Once I had that, of course I had to get the brass caboose from the same catalog.
