I'm designing a series of passenger and baggage cars suitable for an American narrow gauge railroad. There are 30 ft and 40 ft long versions suitable for HOn30 and HOn3. Some general notes: The HOn30 version is a scale 7 ft wide (25mm) , for Microtrains 1015 couplers The HOn3 version is a scale 8 ft wide (28mm) , for Kadee 714 couplers The body and chassis are separate parts , connected by linking 'sprue' which needs to be cut and removed before assembly. The body is designed to clip onto the chassis , no need to glue it on. No interior detail is included as yet. I am working on separate interiors which can be fitted later. Or you could make your own. There are holes in the floor to allow trussrods to be formed from EZ line or something else. See my other rolling stock thread for more details. 5 ft wheelbase passenger trucks are also being developed. I will post more details and pictures when my test prints have arrived , next week.
