I’ve been looking to add a PRR N5 or N8 cabin car (caboose) to my rolling stock. USATrains offers a nice model of a N5 cabin car. Accucraft has a nice model of a N8 model; http://www.accucraft.com/modelc/AL93-051-CABOOSE.htm
Why is there such a massive price difference? USATrains is about $150, Accucraft $500. I own some USAT rolling stock. I own a Accucraft live-steam K4 locomotive. I understand that the USAT model is mostly plastic and the Accucraft is constructed in brass, but what, if any, merit exists for brass constructed rolling stock verses plastic constructed rolling stock?
