Atlas Industrial Rail (IR) made a terrific small 4-4-2 Atlantic steamer. It's about the smallest O gauge steamer I've ever seen, definitely done in 3/16's "S" scale, and it looks great hauling small Marx freight cars. It's cab and boiler and it's tender are inches smaller than a Lionel #1656 0-4-0 switcher. This IR Atlantic is hard to get ahold of now as their diminutive size makes them a valued catch for us "SmO" {small O} pike operators...
