Leslie, great idea!
Having been on the selling side of the counter since the launch of the Murphy Models the one question that
continually pops up is "Can you get me some freight wagons to run with these locos?"
The fact that you are even thinking about producing some gives me great hope, as you say some of the 3D ones just aren't up to scratch.
Small rakes of 3 as an option is another great idea, might cut down somewhat on packing cost etc
Looking forward to some pre production pics !!!
