Well said Ian. 100% Correct! ;-)
Just as a reminder, from page 1 of the thread, here is a prototype shot showing just how much higher the gangway floor is on the prototype. Getting this right has absolutely nothing to do with manufacturing tolerances or the thickness of the checkplate steps in front of the recesses. Let's hope we see some photos in due course to establish whether Bachmann have got this right (fingers crossed it's just the angle of the photo!).
It true that a model is made to a price (in this case, a very high one) so it's not unreasonable to expect a result commensurate with the price. In this case, the additional cost of adding, for example, etched steps or handrails if they help to improve the appearance and proportions of the front end is a price worth paying. In my opinion, getting the shape right is far more important than stuff like interior lighting and DCC gimmickry - and that's speaking as someone who has many sound chipped locos and who is very fond of DCC gimmickry! I can easily add that stuff later, it's less easy to rectify major errors in the shape of a model that might require a full or partial repaint.
