Yes, Virginia (and Jason) -
There really is such a thing as SIX WHEEL arch-bar trucks! Ah done seen 'em m'self!! True, they are standard gauge, but still REALLY unique - one of many special and rare artifacts from the Red River & Gulf RR that you can see at the Southern Forest Heritage Museum. A visit thereto is HIGHLY recommended - especially if you can arrange to be there on a weekend when Everett is on hand to show you around.
