While at Washington Union Station I saw a model of the loco and two cars of the Acela NextGen mode on display in the main hall. What tweked my curiosity is that the gauge looked likr 45mm and the scale more like 1:29 then 1:32. Perhaps 3D printed
Have no idea who modeled it but if the company could be found it would be an interesting discussion about producing additional copies.
Below video link from the platform at New Carrollton this morning.
