 Well, you don't have to believe it, but that is what I understand happened, and they did lease some locos through GE leasing, some SD40 and -2 models, there is also an ex SP Tunnel motor up there as well but it was only used for spare parts. I don't dislike EMD products, I work on them every day, usually as trailing units and they perform OK, but the, and I admit newer GE's that we have are much better, and the cab design which is a lot different than the US versions, is the best we have ever had.

The Frame and the Truck components seem like they would find new locomotive uses elsewhere.

 

I wonder if the prime movers were scrapped or placed in somebody's ship.

Numbers do not lie. C45's are approx. $45000 cheaper to purchase then an SD70ACE; not a lot when your talking about a $2.5 million unit. but when you buy 500 of each it makes a difference.  the month over month availability of the SD70ACE runs between 92.5-93.1% the C45ACCTE's run at 91.3-92.4%. 

GE now has much better product and warranty support then EMD, that is a big decision when buying untested technology.

You would think that somebody at UP would have knowledge of lack of success of the GE turbines, Big Boys, U50's, DD35, DD40 and the big Alcos that all would up in the scrap pile very quickly. Seems like sombody has reinvented the wrong wheel more than once. 

 

-The first batch of Big Boys (4000-4019) all had over 1 million miles on them when retired, the second group (4020-4024) had over 800,000 miles (they came into service 4 years after the first group).  The DD40's had more than that, I believe over 2 million miles on them.  I wouldn't describe these as unsuccessful.

Indeed

 Especially in the case of the Centennials. They were retired more because they were literally worn out after just a decade of use because the Union Pacific depended so heavily on them and they handled most of the system's most important trains. According to the Utahrails website, they averaged 22,000 in-service miles per month and most of the class had racked up over 1 million miles of service before their 5th birthday.

 If anything, they were so successful that they became a victim of it and were literally worn out.

The 9000's, Challengers, Big Boys, DD35's, gas turbines, and Centennials were all quite successful and were very productive for Union Pacific. The steamers gave sterling service for nearly 15 years after Union Pacific decided that diesel was their future and several remained serviceable well into the 1960s awaiting a call to service that traffic levels sadly never warranted. That's a testament to how well they were designed that they were still productuve locomotives for the UP many years after their fate had been decided and most steam had been retired by competitors. And of course, the gas turbine fleet's fate was sealed not because of their performance but because of evolution in America's petrol industry that made their operating cost skyrocket as refinerys found other uses for Bunker C which had largely been considered waste when the units were new.

 The only ones that were anything less then a success in my opinion would be the two GE efforts and the Century 855. Even then, Union Pacific got close to a decade's use out of the U50's. And I've heard several good opinions on the the C855 from those that worked with  them during their short service life. They were a victim to EMD's stellar reliability and the nonstandard nature of the Centuries on the system that did them in, not their performance when they were in working order. And I suspect had we not been in a recession in the late 70s, the U50C's would've had longer service lifes then the 5 years or so they actually had.

If memory serves correctly, the main problem with the U-50-C was the use of aluminum cables throughout the locomotive.  The aluminum could not stand the high heat and "melted", causing fires.  I believe at the same time some of the Alco C-430 were suffering the same fate. The U-50-C's have the distinction of having the shortest life span of any UP loco class, ever.

 I'd love to have some pistons. The biggest piston I have right now has a bore of about 7.5".

The Diesel Engine Trader lists 3 GM16V265H-5 in "runner" condition for "industrial" application, quite possibly from the UP units scrapped in East ST. Louis.
