Good on you Dennis, you know what the time is here!

My understanding is that the GP series of EMD diesel locomotives stands for "General Purpose." They could be used as yard or road switchers, eventually leading to the demise of the "SW" yard-only switchers (though SP and some other roads ran them on short hauls). Some were configured for passenger service with the addition of boiler units. The "SD" stands for "Special Duty" -- i.e., long-haul freight.

My understanding is that the term' definition is as described above by CWEX - any GP loco, 7 and up.

 

Have other people noticed this?  Or do I just imagine this?  In usage, I've noticed that the term "GEEP" seems to be used most often when the loco is a GP loco assigned to yard duty and perhaps suffering a bit from appearance challenges like old paint and a lack of clean up, whereas people will refer to a loco that is more pristine and/or assigned to mainline duty as a "GP9" or whatever.  This is very similar to the use of the word "Jeep" which many people apply to any old, muddy, off road vehicle (at least by the brand, Jeep) whereas they often refer to a Jeep-brand productin a positive way by citing the model number as it "I own a CJ7."

No, he was asking about Geeps, not Jeeps. I believe "Jeep" was popeyes dog.

I thought an SD engine has 6 wheel trucks. They look just like a GP except for the added axle. I guess they are easier on the rails as loads are more distributed with the 3rd axle.

So you personally would call any road switcher where the cab windows are wider than the rest of the body a geep? For example an Alco C420? Because it has a similar body to a GP7 or GP9?

He would, but he would still be wrong! An EMD 4-axle model with the "GP" model designation is referred to as a "Geep" throughout the railroad industry AND the railfan network. PERIOD! Not matter WHAT RICKC calls his model trains!

In the real world (not Lionel versions) SD models are built on a longer frame and generally ballasted (weighted) to axle loadings similar to GP models, so they can achieve considerably more tractive effort at lower speeds with the same HP. Locomotives for USA mainline freight service generally run about 33 tons/axle.

 

EMD GP40+SD40-2

GP40 and SD40-2 have essentially the same 3000HP engines. In this case the SD has a shorter fuel tank, but that is another option that railroads can specify.

dude, they were alco rsd-1's rs-1's were 2 axle. and besides, wernt we talking about emd gp's (geeps)?

 

the below alco rsd-1 was used in WWII to run from iran to russia. i ran this locomotive for quite some time.

Thanks to Nicole for critters I had NOT seen before....! WWII?? era Jeeps on flanged

wheels, in England, or a combat zone?  If that is the power, doubleheaded, too!,  as it looks to be, for that train.    No wonder some farmers back here after the war were plowing with them...

Wonder if any here in North America, like some other vehicles, wound up on flanged wheels holding down branch line mail contracts, or inspection duties?

I think that the first photo was taken somewhere in France in the latter stages of the war. I'm not sure where the second photo was taken, but the trees do not look like northern Europe. There are quite a few images of rail Jeeps on the web, and the locations seem to span the globe.

For anyone in the Norfolk, Virginia area, there is a nice example of one at the Army transportation museum at Ft. Eustius.
