United Refrigeration model railroad in their showroom on Roosevelt Blvd in Northeast Philly. HO scale, 12 x 24, DC. Railroad seems to be professionally made like something you would see in a museum. Very well made with lots of action, ski lift, windmills, helicopter. & trains running in loops. Seems to be all foreign buildings but trains are all American.

I see this. I wonder how they made that choice? Interesting. The helicopter is an interesting addition.
