@Dj'sOgaugetrains I'm pretty sure the I-12 is a bay-window caboose based on a B&O prototype, not a steam locomotive. They've been made before. You might be confusing it with the I10 designation for a PRR Decapod (which have also been made before ;-)
Ah cool. It’s mentioned in the very first post in this thread. I thought it was a small steamer. But yeah now I remember the Lionel caboose. I had one years ago. Thanks!
