Just curious. Does the -DE stand for anything specific? Is it the locomotive model, or something about the drawing?

As a wild guess, could it be specific to the Department of Energy one that was built?
That drawing is from a specific order number 8866012

| U.S. Department of Energy(SROX) | 1 | 106 | Used at the Savannah River Site near Aiken, South Carolina. |
It stands for Diesel Electric. Many schematics I have from many different models have this as well. Especially CSX and BNSF schematics.

Nope. Since the GP line of locomotives are NOT "basic" equipped with dynamic brake, as the SD line of locomotives are, that "DE" on the drawing indicates that it equipped with "Dynamic Brake", with the "Extended Range" feature. Thus the "DE" designation for "Dynamic Extended".

Now lets stop and think,,,,,,,,,,,,why would EMC/EMD indicate "Diesel Electric", when those were/are pretty much all they made/make?

I was just repeating what i was taught in schematic class years ago, your explanation makes much more sense though. Strange how it's not consistent though as i have many schematics of locos with dynamics and extended range that do not designate as DE. Must just be whoever was drawing it at the time. Thanks for the info.
I’m sorry. But the reply that the DE standing for “Diesel Electric” when that’s the only kind of locomotive engine that EMD made is just hilarious. 😂😂😂

They also made slugs as well as control cab locomotives. Makes much more sense now though. Again, just what I was told in class and have never given it another thought until now.
That’s OK David. It just kind of struck me funny. 😉

Me too looking back. I never gave it a second thought as most schematics aren’t made by EMD anyways. Either the specific railroad or a cabinet manufacturer like Elcon.
definitely a Duh moment. 😂

Well...
Plus, EMD built Amtrak's AEM-7 under license with ASEA and GM Diesel in Canada built GF6C electric locomotives for British Columbia Railway.

Sorry but, EMC/EMD never made any slugs. Various controlling "mother" units were offered/built/delivered with "provision for slug" wiring & cabling, but the various customers always sub-contracted for the actual "slugs". EMC/EMD did indeed offer Cow & Calf" sets, but the "calf" still had a prime mover in it, thus it was NOT a "slug".
Makes much more sense now though. Again, just what I was told in class and have never given it another thought until now.

Glad to help. Although I retired from EMD more than 22 years ago (after 36 1/2 years), my memory is still pretty good.

I’m not so good at the historian side of EMD as I am the electrical side, but it’s always nice to learn. (Working on a SD60 as we speak).
