As far as I can tell in the Atlas O Industrial Rail O gauge rolling stock line there has not yet been any Canadian National, Canadian Pacific, and Penn Central.

Would the CN, CP, and PC roadnames command enough demand to be worth producing for these great O Gauge cars?

There have to be some people who like CN, CP, and PC as roadnames for O gauge cars, but have not yet stepped forward and said anything.

A Penn Central plug-door box car, gondola, flat car, covered hopper, open-top hopper, and Center Cupola C&O style Caboose are a set of cars that would economically represent trains that used to operate here in Michigan.

Canadian National and Canadian Pacific rolling stock has been seen frequently in the USA for decades. The CN and CP graphic and color schemes from the 1960's and 1970's can be applied to the IR rolling stock to appeal to both US and Canada O Gauge operators.
