Skagit M.A.C. 4-40 Speeder

Kinsey Skagit

This photo from Darius Kinsey’s “Locomotive Portraits” inspired me to model this speeder.  This is the only ‘in service’ photo I’ve been able to locate so will serve as the basis for detailing.

Here is a photo of a 4-40 from the front.  This is a slightly newer shorter version.

Given that I have no specifications for this speeder, it also provides a known dimension for takeoffs based on the 6′ man theory.  The man in question is on the far right of the photo.  I took his height off the actual photo (2.25″) and the width of the front driver (0.75″).  Based on the 6′ man theory, the drivers scale to a 1:1 height of 24″.  That was a very common size.  The side heights scale to 9″ and the end beams appear to have been 13″ square.  Cab height at the sides would be in the range of 64″.  I based the cab height on the assumption that the two men at the back of the photo are 5’8″.  They appear to be leaning against the speeder’s hood.  This is an angled photo so perspective takeoff techniques will need to be used for other dimensions unless a side or front photo appears.

This photo shows the front portion of the speeder including the hood.  In this photo, stye cab appears to be taller (possibly as a result of complaints about the cramped cab.  This is not an ‘in service’ photo and may be a builders photo of a speeder that is about to be delivered.  It is also likely to be a later speeder.  Cab height scales to 89″ at the side.  Hood height scales to 34″.

I think this version of the speeder looks gawky, so I’m inclined to model the Kinsey speeder.  But this photo is very helpful in coming up with front dimensions.

Here is a photo of a derelict Skagit 4-40 speeder.  The hood is missing but you can see the outline.  Height of cab is more in line with the above photo than the first but windows are taller. Because the deck is missing, a view of the under framing shows.

Finally, the shot of  the cab is from the same speeder.

This photo is of a Skagit 4-30 taken from an article by John Taubeneck in the Oct-Nov 1997 issue of Tall Timber Short Lines.

This photo is of a well used Skagit 4-30 showing the speeder from the front.

This is a photo from the same speeder that is from a slightly different angle.  What is interesting is the part that protrudes from the side of the hood.  But it sets a precedent for widening the hood area which may solve the problem of how to put an electric motor in this area.

This is a rear photo of the same speeder.

This Skagit 4-30 photo is from a Timber Times article written by Phil Holden in issue 51 of Timber Times.  His article also contained the previous two photos.

Phil’s article addresses how to model a Skagit speeder.  the next two shots are of Phil’s model.

Phil’s model was (is?) a static model.  In his article he encourages readers to build one that runs.  Phil, if you are out there reading this, I’m going for it!
