The Pemco Railway System HO-scale trains is probably the shortest lived railway model company in history. It's exact origin is unclear but it appeared around 1979/80 and had seemingly disappeared by 1982.

What we can say is that it's somewhat limited model range were much more detailed than the regular (ready to run) models available at the time and due to certain models being released in Canada there is likely to have been some tie-up with the Aurora Company (certain similar boxes carrying both names).

There is only one known Pemco product catalog, which is undated, but contains color images of most of the models known to exist.
