"MTH Premier O Scale freight car sets are the perfect complement to many of the locomotives featured earlier in this catalog. They also go great with any manufacturer's scale proportioned O Gauge locomotives. 

Each car in these sets is individually numbered for authentic realism. And, each set is available in two item numbers. The second item number features an entirely different set of 6 cars, each also individually numbered, allowing you to obtain a total of 12 different numbered cars if desired. When you prefer the convenience of a ready-to-run unit train, M.T.H. Premier Line 6-car sets are a great choice."
