If you want the LMS Coronation Scot set, may I suggest you wait for the ACE version, which will be scale length, correct windows etc (only the Dining Car is slightly shortened to fit the standard 40cm ACE chassis). These are scheduled to appear at the end of the year to complement the blue ACE streamlined Coronation locomotives now in production. Please note that this is a nearly completely accurate model of the 1937-1939 London Glasgow streamliner, which always bore silver-striped blue livery.
The trouble with the MTH LMS coaches is that they are not flush glazed and the plastic sides are quite thick. ACE use tinplate sides, and their negligable thickness results in the glass being very nearly flush, just as the prototypes were.
In fact, the NYC Drefuss scheme for the 1938 20th Century was very largely the LMS colour scheme in reverse, grey with blue stripes instead of blue with silver stripes. The position of the thick and thin stripes was reversed too, just so it would be less noticieable! These arty-farties never plagerise others, only gain inspiration from them......
It is not the gold-striped red train which ran in 1939 in the USA, and which was displayed at the NY World Fair, 1939 & '40, which was made up from more modern cars, most of which which were supposed to form the 1940 Coronation Scot train but this never ran due to WW2. Cars for the the 1940 train were eventually finished after the War, but never assembled as a unified train.
I am English, but I have the Sunset 20th Century, and the ACE Coronation Scot is on order. It then suddenly occured to me that the NYC train livery was mainly the reverse of the LMS livery, which is most intriguing!
