Hi Joe -
Being a 1:20.3 operator with limited budget I’ve needed to take advantage of some of my smaller scale stock in order to round out my roster. One thing you can do is to up-scale smaller stock. I did this with a 1:24 reefer to create a short 1:20 box car…

The build thread for this car is here: Up-Scaling a Delton Classic to FN3
When there isn’t enough time or ambition for such a project, a simple coupler conversion can put a smaller scale car in service. I’ve done this with a few 1:24 Delton Classic cars. I accept that they are much smaller and justify that with this prototype photo…

I found that body mounting Accucraft couplers on the Delton Classic cars was pretty easy…



I don’t worry too much about the under-sized details. They could be updated with aftermarket castings if they bothered me.
From a distance in operation they look much like the prototype photo…

There is a thread on body mounting couplers to the Delton Classic cars here: Thinking about body mounted couplers for my Aristo/Delton cars
Since I can’t even think about buying any Accucraft 1:20 passenger cars I settled for body mounting Accucraft couplers to some Bachmann Jackson Sharp cars for passenger service…

Again, I don’t let the size difference bother me. When pulled by my 1:20.3 Porter, they look about right…

For some the scale discrepancy is too much to bear, but for me it’s acceptable until such time as I can throw money at the problem!
