All About Postage Stamp Trains
Road Codes

Aurora used three-digit numerical suffixes to identify the road names for train sets, locomotives and rolling stock, which I've dubbed Road Codes. By contrast, Trix used a unique catalog number for each car type/road name combination—something that Aurora started doing (albeit inconsistently) with train sets and locomotives beginning in 1968.

Unfortunately, the 1967 catalog and 1967 Service Manual were the only places these codes were published, and these didn't contain all of them. Since road codes appear only sporadically on packaging, there are a number of them that remain unidentified. If you should find a box or document with a road name and/or road code that's not on this list, please let me know so that I can update it. Thank you!

NOTE: There's a potential conflict in the road codes. 350 is unambiguously Rio Grande, since it appears on a cattle car insert, as well as the 1967 catalog and 1967 Service Manual. However, there's a box marked 4881/350, yet I've found no evidence that a Rio Grande flat car was ever released. The box contains a Norfolk & Western flat.
