I agree on both points. It is weird that the cross section of the locomotive wasn't made to match the cars, but I guess even the new siemens charger+viaggio coaches have that same weird problem:
As far as the paint, the coaches are fine, but the locomotive looks like a healthcare website. I wish they had stuck with the original paint scheme:
Or even better, gone with the original American Flyer paint!
And on the subject of paint - it seems like Amtrak and the rest of North American passenger rail will be adopting the Siemens Charger+Viaggio trainsets. It also seems like Amtrak wants to return to Phase III paint, with red, white, and blue stripes. I think it would be awesome to see a rendering of a Siemens trainset in those colors.
