B40-8 No. 1880, in Houston on 10/17/2007. This was originally SSW No. 8083, delivered May 1989 and painted yellow ten years later as No. 5689. It received this number in February 2004. |
 |
C40-8 No. 9331, in Helper, UT with sister 9343. This unit was received in 1989, part of the same order as No. 9151 above. The C40-8 is a DC-traction, standard-cab locomotive-- some of the last ordered by UP (or any railroad) so configured. Wide cabs became the norm in the early 1990's. |
|
C40-8 No. 9151 in Houston on
10/17/2007. This unit arrived new on the UP in January
1988. These are standard-cab DC units.

 |
C41-8 No. 9078, originally C&NW No. 8566, delivered September 1991, repainted to the UP scheme and number in 1999. It's viewed at Brownwood, TX in March 2001, on the point of a light movement. Directly behind is SP No. 5352, nee D&RGW 5352, an SD40T-2 "tunnel motor". |
 |
C44-9W No. 9718, leading an eastbound autorack train near Carrizozo, NM on 2/18/2008. This DC-traction unit arrived from GE in July 1994. GE refers to this model as a Dash 9-44CW. |

| The AC4400 (or C44AC) was GE's initial entrant into
the AC-traction market, and has proven extremely successful.
Debuting in 1995, it has evolved into several different versions
over time, adding power-management and emissions features to
increase its flexibility and be more environmentally friendly and effecient. One of the subsequent types is the C44AC-CTE. The CTE designation means "Controlled Tractive Effort". Effectively, these units can have their power-on-rail reduced to prevent mishaps with lighter trains or when operating as DPU helpers. The C45AC-CTE is a more recent version of the same general idea, but meets the Tier II emissions requirements (the 45 un UP's parlance does not refer to its horsepower). | |
 |
C44AC-CTE
No. 5717 is shown leading the MDVRO on 12/06/2008. My apologies for
cutting off both ends in the photo. Many interesting details show up
in this close-up, in particular the later CTE-style AC cabinet behind
the cab. Note the three lower X-brake panels and four upper panels.
For comparison, see this photo which
demonstrates the original AC4400 door design. This photo of 5717 also illustrates the grimy state of locomotives working on the tunnel district during the wintertime. |
 |
C44AC-CTE No.5764 is the trailing
unit on an eastbound coal empty passing through Delta, CO on
4/16/2010. It was delivered in March 2001.
The CTE designation means "Controlled Tractive Effort". Effectively, these units can be reduced in power-on-rail to prevent mishaps with lighter trains or when operating as DPU helpers. |
 |
C44AC-CTE No.5908 is the lead unit of an an eastbound coal empty passing through Delta, CO on 4/16/2010. Delivered December 2002. |
 |
C44AC-CTE No. 5912 was delivered
in January 2003 in the "flag" scheme. Seen here on 12/313/2006
in Denver, she's covered in a dark layer of grime, indicative of
hard service in the dirty conditions of the Colorado
mountains. (detail from a larger frame photo)

 |
C44AC-CTE No. 5977 is eastbound at Escalante, CO on 4/15/2010. Delivered May 2003. |
 |
C44AC-CTE No. 6030 leads a westbound load at Roubideau, CO (near Delta) on 4/15/2010. Delivered January 2004. |
 |
 C44AC-CTE No. 6052,
seen at Glenwood Springs on 7/29/2011.Built December 2003 but not delivered until April 2004. |
 |
C44AC No. 6170 was delivered as SP AC4400 No. 353. Here it's running third on a westbound manifest train at Rocky, on 12/06/2008. |
 |
C44ACNo. 6204 was originally SP AC4400 No. 157. Most Espee AC4400's have simply been patched, but this one is a full repaint. The main difference between these units and their "standard" UP sisters is that the cab is not acoustically isolated. This particular one is also from the SP series that did not include master DPU controls, though I do not know whether these were later added by UP. |
 |
C44AC No. 6496 was delivered in June 2000, part of an order of 120 units from that year. Here it's in the helper pool at Glenwood Springs, CO on 9/01/2008. |
 |
C44AC No. 6513, passing eastbound through Escalante, CO (on the North Fork sub) on 4/15/2010. Delivered July 2000. |
 |
Full-Size Image! C44AC No. 6573 is seen at Glenwood Springs on 9/01/2008. Built in April 1997, this unit is only 11 years old here yet is starting to fade pretty bad. |
 |
C44AC No. 6598 leads an empty coal train at Coal Creek Canyon on 12/26/1998. Part of an order of 150 such units, it arrived in May 1997 and so is about a year and a half old in this photo. |
 |
C44AC
No. 6673 is staged on the west end of a string of DPU units at
Glenwood Springs, 7/29/2011. Delivered July 1997, and starting to fade quite a bit. |
 |
C44AC No. 6728 is staged at Glenwood Springs, 7/29/2011. Originally C&NW 8826, delivered December 1994 and repainted/renumbered January 2003. Note the wings, lightning stripe, and the UP shield on the cab (but no flag). |
 |

 |
Chicago
& North Western (C&NW) AC4400 No. 8808 leads a coal load at
Fraser on 12/28/2000. It's in the Operation Lifesaver scheme. Built November 1994 (the oldest AC4400 I have photographed), it was later renumbered to UP 6710 in October 2003. |
 |
C44AC No. 6813, running second on a freight at Granby, CO on 8/9/2007. It was part of an order of 150 units that was delivered throughout 1996, making it one of the older groups of C44AC's on the roster. |
 |
C44AC No. 6819 is on the point of an eastbound coal train, in Pinecliffe siding on 12/30/2006. These units have been ubiquitous on coal trains since their arrival. This unit came in June1996 along with No. 6813 above. |
 |
C44AC
No. 6866 leads a westbound coal empty at Pinecliffe, CO in a howling
wind on the day after Christmas 1998. (It was difficult to keep
a tripod standing in that wind...) Built November 1995. |
 |
C44AC No. 7002, at Grand Junction in November 2002. It was originally leased from GECX as No. 4002 in March 1997, and was repainted in UP colors in 1999. |
 |
C44AC
No. 7124, mid-train at Pinecliffe, CO on the day after Christmas 1998. Built July 1998, it is less than 6 months old in this photo. |
 |
C44AC No. 7277 leads an eastbound empty on the North Fork sub on 4/15/2010. Here it's seen at Escalante. Delivered November 1999. |
 |
C45AC-CTE
No. 7386 is staged in Glenwood Springs yard on 7/29/2011. UP
keeps helper (DPU) units here during the warmer months when the
engines can be shut down. Built March 2009. |
 |
C45AC-CTE No. 7763. This unit arrived on 9/18/2007, and was exactly five months old when this shot was taken on 2/18/2008. See here for an explanation of the model designation. Notice the variant on the paint scheme: there is a yellow stripe on the lower portion of the radiator wing. |
| GE's AC6044CW model was analogous to EMD's SD9043: it is a C60 carbody with a 4,400-hp prime mover installed, convertible to a 6,000-hp motor if desired later. UP's designation is both C44/60AC and C6044AC. | |
 |
C6044AC No. 7026 is the trailing unit
on a westbound coal empty in Glenwood Canyon, June 2003.
Judging by the coat of grime, this one has been working hard.
In UP's number-juggling system, this unit became 7352 in May 2005, then 7046 on Jan 13, 2009. |
 |
C6044AC
No. 7034 is staged in Glenwood Springs yard on 7/29/2011. Delivered January 1996. This unit was not renumbered with other C60/44's; it has kept the same number since delivery. |
 |
C6044AC
No. 7038 is staged in Glenwood Springs yard on 7/29/2011. Delivered December 1995. This unit was not renumbered with other C60/44's. |
 |
C6044AC No. 7048, Grand Junction, November 2002. This unit was renumber 7374 in March 2004, then 7321 in September 2008. Note the radiator which extends beyond the long hood, the distinctive feature of this model. |
 |
C6044AC No. 7060 is running second on a westbound load at Roubideau, CO on 4/15/2010. Delivered September 1996, the same month as the merger with SP. This unit retained its original number, unlike many of its sisters. |
 |
C6044AC No. 7311 is seen passing through Delta, CO on 4/16/2010. This convertible unit was built in March 1998. |
 |
