I am proposing a DRGW or a DSNG Silver Vista #313 railcar, built in Alamosa in the 1950s as narrow gauge and was used extensively on the Silverton/San Juan Branch (all 3' narrow gauge - today parts of it remain as the Cumbres and Toltec and the Durango and Silverton). Either Nn3 or N scale is perfect - however, Nn3 would be more realistic, but then more people have N scale over Nn3. Here is a DSNG website link to the modern day Silver Vista (replica - original destroyed in a fire in Alamosa in the late 1950s): https://www.durangotrain.com/classes-service/first-class/silver-vista/ Any intrests?
