Nice Looking cars and Cabeese! Did those 15" Aluminum Passenger cars come like that or were they modified to add detailed interiors??
On the sharing side.....
You've probably seen this pic already, Atlas O 8359B, as I've posted it on the "Buy anything cool lately" topic. Atlas makes some nicely detailed refer cars. This is modeled after one of the two all aluminum UP/SP PFE refers.
Another car I would like to share is one that most scale modelers/runners might not take a second look at:
MTH 30-7915 Union Pacific Searchlight Car
Obviously not prototypical. More than a few years old too. More of a homage to O-27, but it's bigger almost scale in size for a depressed flat car. The six wheel trucks add a lot of weight..it's heavier than you think it would be. Both trucks have power pickups.
I like the color scheme..while it's clearly just for fun, it doesn't seem completely toy-like and actually looks pretty good in a consist behind scale UP steamers.
(unless of course you're going for the realism of modelling 3:47 pm May 15th 1958 at Sherman Hill..etc...etc..)
But it is something different to catch your eye.
Enjoy.....
