American Flyer S Scale Hudson 4-6-4 Locomotives
Unless otherwise specified, the large pictures on this page are from the collection of The Upstairs Train.

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

When I get all the pages built, you will be able to click on an engine picture to see the train sets it pulls.  At the moment, it works only for the #21130.
#320 New York Central Hudson made in 1946 with New York Central lettering.
Following Gilbert numbering conventions,
the #320 is the basic engine without smoke unit or choo-choo sound.

Similar #320 New York Central Hudson made in 1947 with AMERICAN FLYER LINES lettering.
#321 New York Central Hudson made in 1946 with New Your Central lettering.
These Hudsons did not follow Gilbert numbering conventions for the Atlantics;
the #321 engine has choo-choo sound and smoke unit in the tender, like the #322.

I am told that the Maury Romer interviews said these cut aways were made so the directors could see how things worked and approve or disapprove production of an item. These cut away locos were then used in the corporate sales center on the second floor so buyers from big stores like Sears and Macy's could come in and see what the product was all about, how it was made, and how it worked (and check out the massive layout up there) before they made their orders. When the change was made to smoke and choo choo in the boiler, these were used to show how everything fit and worked in the boiler.

#322AC New York Central Hudson made from 1949 to 1951 with AMERICAN FLYER lettering.

Here's a close-up of the engine by itself.  It used the Air Chime Whistle control with tube.

And its tender.

Early #K325 Hudson engine with screwed-on knuckle coupler made only in early 1952.

#K325 Hudson engines made later in 1952 had crimped-on knuckle couplers that became Gilbert's standard.
(This is a picture I took of an engine in Jack Larson's collection.)
#326 New York Central Hudson made from 1953 to 1957 with AMERICAN FLYER LINES lettering.
It came in two versions, one with Gilbert's standard motor and one with a larger motor.
Rare #21129 New York Central Hudson made only in 1958 with AMERICAN FLYER LINES lettering.

#21130 New York Central Hudson made from 1959 to 1960
with plug wire connection between engine and tender.
The #21130 appeared in only three freight sets; click the picture to see them.

#21130 New York Central Hudson made from 1962 to 1964
with direct wire connection between engine and tender.
Unlike most Gilbert engines, there is no plug on either wnd of the wire;
it goes from the tender up under the motor in the engine.

Lionel announced but never sold two Hudson locomotives under their American Flyer name in 1988:

#48200 Wabash

#48201 Santa Fe

Are there any prototypes or mockups out there?  Can anyone provide a picture of what might have been?
