My comment wasn't directed at you per se.
I know that's what Trix named it.
But the U28C and the old Rivarossi "SW1500" are the two worst examples of mis-named models in N scale.
My guess is.... in the 60s and 70s, a new loco version would come out and someone with drafting skills would draw it pretty quickly for a modelling magazine. And so since a loco was brand new, there was the possibility for mis-information.
The Trix model IS a model of something. But if you want a more accurate "U28C" you would need to kitbash it.
