Plymouth D
Revised January 23, 2005

The above photo shows the "HO" Plymouth with an S scale F unit.
How close is this to correct S scale?
There are many prototype Plymouth photos at:
http://www.northeast.railfan.net/diesel123.html
The ones that most closely resemble this unit are the DDT 12 ton units.
Note how the width of the unit is almost the same as the track gauge?
This is a very small unit, the model is probably a bit large for correct S scale.
HOWEVER
I found dimensional data for one unit that looks VERY similar to this "HO" model;
the ratio of hood width to cab width is less on the prototype.

Here are the S scale dimensions of the model compared to the above unit.

	Prototype	Model
Length	21' 1"	22'
Width	8'	8'
Height	10' 6"	10' 10"

It certainly is extremely close in size if you ignore hood width.
Regarding the length, the model has a small toolbox(?) behind the cab, so it is ok for the model to be a bit longer!
Note the man in this photo;

I placed an S scale man next to the model, and his height against the model is almost identical to the height of the man against the prototype.
I say that by stretching your imagination just a bit, this unit is usable in S.
