Instead of pointing fingers you should contact the "owner" of the original you feel was used for this drawing and tell him his intellectual property was stolen. Then you can straighten your Boy Scout hat and call it a day as you did what you should have done.
The DDA40X wasnt a failure. Check out Don Strack's stuff on them. They accomplished a lot in a short time frame. For what UP had in the way of trackage back then, they seemed to have worked fine.for it ever to be considered it will have to wait until those familiar with the problems with the DD40 are retired and some real noobs get high enough to make such a poor decision. In retrospective, the DD (DDA40X, DD35, et al) were a failure. Mostly for reasons that Pat mentioned: inflexibility, high fixed costs and lack of volume/scale. A totally unique engine with limited flexibility is a dead horse for a modern railroad.
I wouldn't hold my breath....
There is a big difference between an Engineering success (it was, altho shortlived) and a Business success (it wasn't ever).They accomplished a lot in a short time frame.
they're permanently safe in your dreams, Glen.....Heck with the new SD's, I'm still waiting for EMD to catch up on the GP's!!! Where are the GP70's, 75's, 80's, and 90's?????
The DDA40X was definitely a success. However they were an unconventional design, designed jointly by EMD and UP. A new CMO came along with a different philosophy which was to acquire standard production model locomotives which led to the demise to future double diesel road units like this. These units racked up several million miles before retirement and maintained high availability ratings up until the end. These units were built for specific purposes and comparing them to a GP40 or SD40-2 is nothing but comparing apples and oranges.There is a big difference between an Engineering success (it was, altho shortlived) and a Business success (it wasn't ever).
Bottomline is that if they had been a true success, Engr + Business, they would have ordered more of a similar nature, or at least evolved the concept further. They didn't do either and the replacements were no-frills, single PM SD40-2 for tonnage or GP40 for speed. Both of which are still in Class 1 usage 30+ years later and major investments are being made to continue their life even further. That's success. Even when the SD40-2 was being phased out of primary usage, the replacement SD70 was based on the concept of the SD40-2 (no-frills, single PM).
