This is undoubtedly THE BEST passenger car I have ever had and likely ever will, the GGD Daylight 3/4 dome car, shown first below as it came stock:
Notwithstanding the excellence of the stock model, I basically tried to make the interior as realistic as well as colorful as possible with a full house of passengers, especially in the dome lounge area:
The body and interior dome floor are brass as are the prototypical leaf motif screens - I only messed with Scott Mann's fine product because I thought it deserved the full treatment inside. I studied the SP prototypes at length for ideas although this rendition of them is not an exact duplicate of any particular one.
There is a "how to" thread about this car posted over on the 3Rail Scale section, but as I have been running this car in its completed form for a few weeks I thought it was a good candidate for this thread. The background explanation is here: https://ogrforum.ogaugerr.com/...-get-at-the-interior
