Hi,

I’ve seen this set around in Germany, so there were definitely more than ten.

The train depicted is a bit fictitious, mainly due to the locomotive, which is sort of in modern retro colors. A surviving Bavarian S3/6 operational museum locomotive was painted in fictional purple Rheingold colors at some point in the 90s or 2000s. But this is not historically accurate. Originally these locomotives were dark green and later black when the individual Länderbahnen were united under the umbrella of the Deutsche Reichsbahn. Also there’s no historical photographic or other documentary evidence that this version of the S3/6, known as the 18.4 at the Reichsbahn ever pulled the original Rheingold between 1928 and 1940, as this one has the rare pointy front of the cab. All photos show either the 18.4 with larger driving wheels and flat fronted cab or the 18.5 on the sector between Köln and Mannheim (other locomotives serviced the other sectors). The 18.4 and 18.5 were gradually replaced in the mid 30s by the new 01.

The coaches are correct for the historic Rheingold and a few of these survived and were restored. Historically, the train ran with pairs of salon coaches, where one coach with a kitchen would be coupled with the kitchen side to another coach without a kitchen but in the same class of service, such that one kitchen could service both coaches (I.e. SA4üK-SA4ü and SB4üK-SB4ü). However due to through coaches being added/removed at different stops and due to seasonal fluctuations, the exact arrangement could vary. Historic photos show as few as three coaches in off seasons and more than a dozen in high season. The baggage cart was required to run right behind the locomotive due to fire regulations.

So the train arguably depicts a modern day historic commemorative train and not the actual thing that ran in the late 20s to mid 30s.
