Today is National S Gauge/Scale Day! (Officially unofficial...)
So, time to celebrate a little evolution.
A locomotive that helped to start it all; The C-D Models wood/card/metal 4-6-0:
The Iconic AF Atlantic:
The SHS 2-8-0:
Doubtless, there are many more locomotives that could be shown, I've chosen these three to represent the "holiday" today
