Union Pacific GE AC4400 consist

[eddie_b]

Does anyone know what type of consist the UP would have teamed the GE AC4400 up with. I cannot find any relevant information on the net.

Any help would be appreciated.

Although that is true (if somewhat flippant and rude), in actual practice, UP generally runs it's AC4400CW's on coal trains...the only other locomotives that routinely team up with the AC's in this kind of service are "SD9043AC"'s (UP's term for SD90MAC's with 4300 HP engines) and AC6000CW "convertibles" (similar in nature to the SD9043's, they are AC6000's with 4400 HP engines). There are always exceptions, of course. I have seen AC4400's in merchandise service (especially the CTE variants in the 5500-5999 series). Here in the St. Louis area, UP coal trains generally run with two locomotives pulling and one pushing. Variations observed (usually on empties) are one, two or three pulling and none pushing, one on each end and, rarely, one AC4400 pulling 135 empties. Most AC's are in UP paint, but those in original SP & CNW paint still appear, although most of those have been renumbered.

You have a lot of nerve and your comment is uncalled for. Especially for implying I posted "with an attitude" when I answered a broad question.

I've seen a AC4400 with GP units, SD units, other AC units, ES units - anything with those prefixes. Each is in the following photo complete with UP 4400, SD wide cab, SD, ES44, and GP unit (under overpass).

Hence, anything with an MU system.

Don't be a jerk about other people's answers.

Thanks for your answers guys, you have helped me to work out how my consists should be run on my UP railroad. Thanks for the photo David, was good to see a real life consist up close and personal.

We don't get too many like that in New Zealand.

Kind regards,

Eddie

I think what eddie b was asking was "what kind of train would UP AC4400's usually pull" not "what kind of engines would UP AC4400's usually run with".

...which is what I tried to explain.

Well yes that was my point, you and David were answering two different questions - he was saying AC4400's could be put together in an m.u. consist with pretty much any other diesel the RR owned, you were answering about what type of trains AC4400's would pull. So both answers were correct...in the right context. [^]
