There does look to be one difference in this new C58 and the original one I have....the number plate on the new ones smokebox door is gold with a blue background where mine is gold on a black background. This could be a way to tell the differences in releases if, in fact, the real one released comes with blue. As far as I can see the drumhead is the same and I can't tell if the number plates on the sides of the cab have a blue background or not.
EDIT: Just noticed the smokebox door handle is gold in the picture of the new one where mine has no color also there are gold bands around that cylinder above the door that is not on mine but I have seen several times before that the released trains sometimes do not have the same details as the first images especially when it comes to gold.
