All About Postage Stamp Trains
Trix's model is correctly referred to as an F7 in their catalog, whereas Aurora inexplicably changed it to F9, which is incorrect. That said, the only difference between the two locomotives is the pattern of grilles along the side. They were both manufactured by the Electro-Motive Division of General Motors; the F7s were produced from 1949 to 1953, and the F9s from 1953 to 1960.
To my knowledge, a Pennsylvania F9-B was only available as a dummy.
Note that it's very difficult to find B&O diesels in good shape. The gold printing is not durable: it fades, and is sometimes almost completely worn off by the Styrofoam nest. Also, the light grey paint chips easily.
Production of these locos continued until the late 1990s, when Trix went bankrupt, and their buyer, Märklin, ended the production of all North American models. In addition to being sold under the Minitrix brand, they were rebranded by Model Power and Con-Cor.
Example Box Labels
Given that each road name has a unique catalog number, the road codes included on the packaging seem a bit redundant. Odd, too, that they didn't always do it.
