American Flyer Northern Steam Engines (1 of 2)

Gilbert called it the Challenger but the railroads called it a Northern.  The Challenger was a different engine.

Gilbert made thirteen Northern Locomotives and Lionel has added nineteen more under their American Flyer name. Because there are so many, I have split them up over two web pages:

          Gilbert Northerns are on this page.
          Lionel  #48047 through #48064 are on this page
                      #42562 through #47953 are on page 2
                      #2021110 through #2021160 are on page 2

Unless otherwise specified, the large pictures on this page are of engines in the collection of The Upstairs Train.

If you have a picture that you would like to share with the world of any of engines not shown here, or a better picture of one that is shown, email them to me: theupstairstrain@gmail.com

As I get pictures of the sets, you will be able to click on each engine to see the train(s) it pulled.


The #332 Union Pacific Northern made from 1946 to 1949 came in six versions:

An AC version with silver Union Pacific lettering and smoke unit in the tender made only in 1946

A DC version with white American Flyer Lines lettering and smoke unit in the tender made only in 1947
(Picture courtesy of an anonymous donor.)


A pre-production prototype with smoke unit in the boiler made only in 1947
A DC version with white American Flyer Lines lettering and smoke unit in the boiler made only in 1948
I think this is another example of the same version.

A similar DC version with white stripe on the running board made only in 1949.

#K335 Union Pacific Northern made only in 1952.
(This is a picture I took of an engine in Jack Larson's collection.)
The first ones made had the
riveted knuckle coupler attached by a screw.
Like the #326 Hudson, the K335 was made with two different motors, one larger than the other.  The large motor is above and the small one below.

Here's a comparison of the two armatures.

Gilbert made these "cut-away" engines for dealers so they could show people what was inside.
The other side looked perfectly normal.
My #336 Union Pacific Northern made from 1953 to 1957.
#21139 Union Pacific Northern made from 1958 to 1959.

In 2005, Lionel released their first American Flyer Northern locomotive and is still releasing new models.
