To me, the 2nd CN picture says model or toy; I would never mistake one of these overland models, for the real thing.
BTW, my opinion is formed by simply looking at the model itself. You can doctor... when photographing, to help make the model appear more realistic; but, I'd like the model to appear realistic, just by looking at it, in any setting.
For me, the missing "presence" is just one of the factors, there are others. I intentionally didn't use the word toy-like, some of you would take that as an insult; but, everything I've seen so far,including my own models, to me, has a toy-like appearance. Nicely crafted toys.
I've got two new MTH Premier scale wheels 3.0 GP35's ordered; P&WV and Santa Fe. I'm curious to see how realistic these models will look?
High-nose models can appear a bit more massive; but, I just recently traded away my new MTH Premier 3.0 Canadian Pacific Train Master; it only had 6 scale miles logged on it. It was part of the trade for the brand new GP35's.
After I receive the GP35's, I don't have any plans for any more new locomotives. That's winding down for me.
BTW, the more I became educated, re: the prototypes, the less I enjoyed what I have and what I've seen... It's ironic, I think I actually got more enjoyment during my initial involvement with this hobby. After a while, very few things measured up...
