If my bubble wrap measurement (a 40' N scale car is 7 bubbles) is accurate, that is definitely HO.
That would be a fun 3-D print project for a Tomix chassis... no?

I dunno. I think if you are going to do an old boxcab, it should have old power. Arnold Rapido 1970-ish chassis, or something like that.
But kidding aside, it is surprising that there aren't a bunch of 3D prints out there for boxcabs. Often the first diesel for a lot of roads- certainly iconic- everything from little switchers to the original power for the Super Chief (literally numbered "1" although not ATSF's first diesel). A lot of them still around in the 1950s doing duty as light duty switchers. GTW had one that worked the ferry docks in Milwaukee until 1959.
