Overmod Have seen it, and it's fascinating. If anyone wondered what an electric DD40 with double cabs might look like, nearly 90' long ... here it is. Still more interesting is that it's rated only 100 more hp. than a diesel with the same trucks. Is this traction-motor limited somehow?

Perhaps. The GP40 from that time period handled only 750 HP/motor. The GM6C and GF6C were rated at 1,000HP per motor but they were 10+ year later designs with E88 traction motors with the same stator size as the D77 but better insulation and cooling.
Dave,
I have the same P&W pocketbook I got from my Stepfather years ago. Amazing reference.
Thank you for sharing your knowledge!

oltmannd How about an EMD DDR, 6700 HP electric? I have an EMD spec/proposal to the PRR dated December 1966 with the details.... Gen'l arrangment... https://photos.app.goo.gl/2f7AcDwXpwgx

Before my time at EMD, but I immediately recognized the handwriting of Frank Lapka, a terrific designer who retired about 1978 after 40 years at EMD. While working on a design project with him, he gave me a Pratt & Whitney pocket book on aircraft engine design (that I can't find at the moment) that he was given by Gene Kettering to aid him in a radial engine design he was doing as a "government job" in the 50's. The layouts exist in EMD's files so make that an "engine proposed but never built".

oltmanndHow about this? https://drive.google.com/file/d/1KewDcBGdzsTuWVOg2hCPURMiAaV5YwXH/view?usp=sharing
Requires me to have a Google account (more specifically, access to the Google Drive service), and then requires me to 'request access' once I'm signed in. I asked 'whoever reads the messages' on a request for access to contact you directly if you meant to give blanket permissions to forum folks.
This is particularly fun as my registered email for signin is different from that used for the Google Account ... don't ask, it's a history thing. Remains to be seen what form 'approval' to the resource is granted ... and on what e-mail address it will appear.
Thanks already for the thoughtfulness in providing the material for access -- many more thanks when I get to read it!
EDIT: Got the permission link. Oddly the file, although I can read it perfectly well on a phone, will not load into iBooks.

Convicted One ANDREW BOYD So what are some proposed but unbuilt locomotives you all have read or heard about? I don't believe that this Raymond Loewy design ever made it into production. http://www.art.net/Lile/loewy/images/bureuloc.gif I believe those are cylinders and driver rods along the side

That loco in the link you posted almost looks like an early prototype of C&O's M-1 Class Steam Turbine
ANDREW BOYDSo what are some proposed but unbuilt locomotives you all have read or heard about?
Lehigh Valley 4-4-6-4; NYC C1a 4-4-4-4
Baltimore & Ohio W-1 motor locomotive
PRR V1 turbine (several variants)
Anything with Franklin System type C poppet-valve gear, or double Belpaire...
We have a couple of very extensive threads on diesels catalogued but not built; it turns out there is technical data on the Ingalls Shipbuilding 2000hp single-unit passenger locomotive.
In recent times, one of my favorite things to think about regarding railroads has been proposed locomotives that were, for any number of reasons, never built. So what are some proposed but unbuilt locomotives you all have read or heard about?
So far, I can personally think of:
- N&W Y7 2-8-8-2
- ATSF Cab Forward 6-4-4-4
- Erie 2-10-4/2-6-6-4
- Monon 4-10-4
