Youn don't know what confused is. Wait until you are 90.

Greg,
I got my information here:
http://www.thedieselshop.us/Data%20EMD%20GP9.HTML
http://www.thedieselshop.us/Data%20EMD%20GP35.HTML
It looks like your measurements compare to the center bolster measurement on
this website. I'll check my ICG locomotive diagram books as I'm all but
positive they'll have the measurement right. In any case, there is a difference
and it is noticeable. Especially if you pay attention to the distance between
the trucks and the pilots.
It was also pointed out that I was incorrect on the truck axle centers. It's
the EMD trucks that are too big by 4" rather than the AAR Type B trucks being
too small by 4".
I buy into the notion that we build caricatures of railroads moreso than
exact scale models of railroads. Once one gets over the fact that they can't do
everything to exact scale, it becomes a matter of degrees as to how much
caricaturization you'll accept. For me, it has to look right to my eye. I won't
stress over 6", but 12" or more (in any scale, I've found) will require some
neat visual tricks to get it to "look right".
Best Regards,
Rhett Graves

31' centers and the GP35 had 32' centers. I checked two sources for the
prototype and they both matched on the truck centers. Drawings from RMC tend to
have errors but the drawings in Mainline Modeler are accurate and those are the
references I was checking. So I measured my AM GP9 and it comes out to 31'9".
It appears that the AM GP9 has a centering of 9" too long and AM GP35 is only
3" too close.

drawings and all the info I've accumulated over the last 40 years.

is good. The trucks are just too close together.
