Large 4-4-0?

Large 4-4-0?

Postby AstroGoat760 » Mon Jan 29, 2018 3:46 pm

Looking in one of my parts bins, I found most of a GEM 4-4-0 kit, including the full frame, and a damaged body.

It does not have the deep flanges like Tri-Ang wheels do, and seems to work just fine with the Kuehn track and switch that I have just fine.

The driving wheels are about 0.70" tall, which is within the size range used by larger 4-4-0s in the United States.

Does anyone have any prototype recommendations for the body?

Here is the main frame on a Keuhn switch:

Here is the full chassis. I do have a worm that will fit the worm gear as well.

The most common use of 84in drivers in the US was probably for 4-4-2 Atlantics...

You would need to move the rear axle forward... and find a trailing truck (HP?)

I do have spare trailing trucks, but I kinda have my heart set on a modern style 4-4-0 with a shotgun stack.

NP-666 is a pre-ToC engine... with only 63in drivers and square steam chests.
Ref: http://www.nprha.org/Steam%20Diagrams/Class%20B%20Diagram%201900.jpg
Note: The diagram is from 1900... but the engine was built in 1887.

Here is a 'modern' 4-4-0... albeit with 73in drivers;

SP E-27 4-4-0
Given the 84in drivers... I still think you will have more luck finding a 4-4-2 Atlantic than a 4-4-0 Eight-Wheeler.

For me, a "modern" 4-4-0 denotes coal burning with outside cylinders, and has a straight stack.

The driving wheels that I have are, without the flanges, 0.72" tall, which would translate to 72" drivers on the model. I do not think that I will find an exact match for the GEM frame in North American proto, but I am sure that I will be able to find "Close Enough".

New Math???
0.72" X 120 = 7.2 FEET in TT... i.e. 86.4in

If you build something you enjoy... my comments are completely irrelevant.
It is your model... your components... GO FOR IT!
