Shane, I agree about the ride height and/or tilt discrepancies. And agreed, I think that is what is being shown in the pic above. I was more struck in that shot by the huge damper(?) between vehicles that I had never seen before.
Regarding the vehicle at the heritage centre though, I will measure next time I am up there but the stripes look genuinely in a different position.
There is so much additional detail that you can see in these shots. Personally, I'm looking forward to modelling some of this. Just look at all the pipework coming out of the axlebox! I know Hornby have modelled some of this but I think there is much scope for improvement here on what they have done. At least the basic shape is right this time so we have a good base model to start from.
I think the vehicles might be able to be closely coupled with a bit of tweaking to the bogies.
