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

The #336 on this page is from 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 it to me: theupstairstrain@yahoo.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.
