Well I,m convinced its a photo of an engineering prototype, to be made mostly from plastic unlike the 700 which is mostly die cast. If it was CG, you would normally either choose CAD (each part in a different colour) or you would go the whole hog and decorate it to show what the final item will exactly look like. The latter asks a lot of effort which would not be worth it.
On the other hand the images may have been tidied up in photoshop, taking out unwanted glares, background clutter etc, so your eye is on the model. ( the model is the hero of the shot after all).
I agree it looks more detailed than most railroad but clearly not up to Bachmanns 9F. Of course such an engine will have a very basic paint scheme unless they get their weathering act sorted out, but to date they have not been convincing here.
I,d say this was a true mid range model, not strictly railroad nor main range. Perhaps they need to start splitting the range into 3 parts now...
My decision to buy will be if one is numbered 92029, the only one to turn a wheel briefly on southern...
