Is it because the B39-8s are less expensive and/or a better value, or are the SD90MACs really that bad?

Do these 90's have problems?

I recall reading somewhere that they are off lease, and UP decided not to renew the lease. I guess it was like a five or so year lease.

It seems that they are simply too much locomotive for what the railroads need today. A train that would only require one loco runs the risk of getting stranded, while ive read that they don't MU to well with other locos and just sort of drag them around.

History does repeat itself - there is quite a history of high horsepower locos that weren't quite what they were thought to be, and not as successful as they could/should have been, and led relatively short lives. the gas/turbines, SD45X, any dual engined loco, U50, DD40, DD40X, DD35, didn't Alco build one C-640 too?

Probably KCS found that 6000hp/unit was too much.

Also, there wasn't a C-640, but MLW did build a M-640. It is preserved in a museum near Montreal.

its simply because the lease on the SD90MAC-H's expired. They were on a 1 year lease from EMD. It was this time last year when the units started to show up on KCS.

ALCO built the dual engined C855- 3ea built, A-B-B. All went to the UP and all only lasted about 10 years before going the way of the torch. But wow did they look brutal!

EMLX sure did a great job of desecrating the UP paint job and logo. :-D Wonder why UP has not sued them yet.

The M-640 was not a dual diesel engine design. It was an single 18 cylinder Alco 251 Prime mover.

How do you know that it wasn't UP who blacked out the logo and blacklined the name before they handed the units over to EMLX? That is usually the procedure.

If UP did it, they would have covered all traces of the Union Pacific letters to protect its corporate identity, instead of looking like a vandal job.

Regardless, I doubt UP will be suing EMLX just because the Union Pacific name is still visible. :P If UP was really that concerned about it, I'm sure corrective measures would have already been taken -- e.g. completely blacking out the letters.

es80ac there are too many for Union Pacific to sue.

Stick to guessing about "Union 76" gas balls. Derating HP is certainly one very effective way, to avoid failures from over-working. Taking every reusable part off? For what, rebuilding another SD-90? Railfan fantasy, and conjecture, is a far cry, from the reality of railroading. Try to guess about something, in the TAMR forum.......... :P

This could also be a largely financial transaction - perhaps the other guys offered more attractive lease terms for the other units.
