All About Postage Stamp Trains
F9-A Diesels

Catalog Numbers


  • 4861/210 Union Pacific
  • 4861/211 Canadian National
  • 4861/220 Santa Fe
  • 4861/230 Pennsylvania
  • 4861/240 Baltimore & Ohio

1968, with headlight:

  • 4848 Santa Fe
  • 4849 Penn Central
  • 4850 Baltimore & Ohio
  • 4851 Union Pacific

1968, without headlight:

  • 4858 Santa Fe
  • 4859 Penn Central
  • 4860 Baltimore & Ohio
  • 4861 Union Pacific

Note that 4861 creates a conflict of sorts with the 1967 series. Also, the Canadian National unit is a legitimate Postage Stamp release.

Note that it's very difficult to find B&O diesels in good shape. The gold printing is not durable, and is sometimes almost completely worn off by the Styrofoam nest; also, the pale grey paint chips easily. Likewise the dark grey paint on the Union Pacific scheme is prone to chipping. In all cases, the horns are often a casualty from rough handling or, as is most often the case, being placed in the set tray backwards.

Incidentally, all F9-A units are numbered 510, regardless of road name. Why? It may have to do with the fact that 510 is molded into the number board inserts. Also, this loco is referred to as an F7 in the Trix catalog, which is a little closer to the mark; it's anyone's guess why Aurora changed it to F9.

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

Since 4850 is a road name-specific catalog number, the road code on the second box is redundant. Odd, too, that they didn't always do it.
