As many of you know, Lionel purchased the molds/tooling for these nice cars from Pola and produced a limited number of reefers, boxcars and gondolas in their "Standard O" series in the early 1970's thru the mid 80's. The underbody details are molded into the frames and the diecast sprung trucks are also nice. I started with the Stroh's reefer and recently added the GT, Schaefer's, Clark, and Miller's reefers and the NYC gondola, plus a B&O Sentinal boxcar. I have a nice Lionel 6907 1/48 scale caboose with low cupola to round out the train. My VL Hudson is on the point of this freight consist!
Although these cars are 1/48 scale, they have a "toyish" look that makes them a kind of hybrid, and that is what appeals to me!
