Here we have the Theo Berlyn example of the locomotive slash passenger train that couldn't..
D&RGW's infamous 1941 Over-night to Salt Lake City Prospector, the businessman's friend.
I have no idea who built the models; only Korea. I do not like the "etched" fluting a LMB era thing dating from the 1960's. I am surprised this late in the game; 2000 Theo etched the fluting rather than the established method PRB used or DVP since the early 1990's pressing the brass into the shape of the fluting and adding it as a separate part. A far better way to do it IMHO. It is not like he didn't add all the right detail. The interiors are fantastic; correctly decorated.
