SD50, C36-7 and others...MoPac Diesel Power - UP Merger
The 'Canaries'

The merger line-up of 1982. Missouri Pacific SD40-2 #3157, Union Pacific SD40-2 and Western Pacific GP40-2 #3546, all in fresh paint, pose for the official merger photo in 1982. - Photo Courtesy Union Pacific System/Jay Glenewinkel Collection.

As the merger between the MoPac and Union Pacific was finalized, the "Jenks Blue" paint scheme was replaced by UP's "canary yellow" with the name "Missouri Pacific" in block-lettering on the sides. Gradually this was replaced with the Union Pacific name in MoPac style block-lettering. After a few short years UP repainted over any remaining MoPac owned engines with it's own name/lettering.

When it was all added up, MoPac and it's subsidiaries had rostered a total of 3,062 diesel units over its lifetime. It was among of the most modern rail fleets around. On January 8, 1980, the Union Pacific announced the initial agreement to aquire the Missouri Pacific. MP was a 11,469 mile system to UP's 9,420 miles. By May 1983 the process of the union of the two systems began. One era ended and another began, most visibly with the repainting of Mopac's locomotives into UP colors while retaining the name "Missouri Pacific" painted on the sides.

The MoPac and UP were to operate as indiviual railroad companies - though under one banner - during the initial merger period. Both roads were so large that critics of the newly formed mega-railroad said it would collapse under it's own weight. With the addition of the Western Pacific the super system was indeed the biggest merger ever of the day. However, the operations on both roads were so similar, in fact, that the melding of UP's powerful connections with MoPac's powerful transportation went smoother than expected. After operation were consolidated in 1986, the Union Pacific System was created. Though Union Pacific and Missouri Pacific were still seperate companies, they operated as one. Complete control of the Missouri Pacific was acquired by Union Pacific in 1997.

Even until today, the MoPac fleet was among the largest to come to the UP system, second only to the Southern Pacific's, which UP bought almost two decades later. Approximately two-thirds of that fleet is still in UP service as of January 1, 2001.

An interesting fact is that even as MoPac locos where beginning to be repainted to the new post-merger scheme, UP itself adopted MP's variation on the standard UP scheme. MP initiated the trend of painting the trucks grey instead of UP's silver as well as the anti-glare panel on the top of the short hood was painted grey instead of UP's standard green.

The Beginning of the End

In January 1984, Missouri Pacific announced that it would begin repainting it's locomotives into the Union Pacific Yellow and Grey paint scheme, and apply the road name "Missouri Pacific" to the car bodies.

In that same month, a locomotive was needed for a test scheme. The task was to be done in North Platte, Nebraska. At the time, there were no MoPac units available, so a shopped Union Pacific SD40 #3030 was repainted and lettered "Missouri Pacific" using UPs standard rounded lettering.

A few publicity photos were taken, and the unit was placed back in the paint shop two hours later and relettered to UP #3030. This was the shortest lived MoPac unit ever.

After the test unit was painted, it was decided that the letters were too large to fit on the side of the MoPacs smaller GP units, and so the block lettering was used.

The #3030 unit was indeed a test unit for the MP Canary Schemes. On a side note, MP GP40-2 #662 also recieved similar rounded MP lettering, but these were the only 2 units to have the rounded lettering. (J. Glenewinkel)

New Missouri Pacific Power that Never Wore Eagles

There were three different motive power models that MoPac owned after the merger with Union Pacific had begun. Two were purchased, the third was owned on paper. These were the EMD-built SD50 (5000-series), the C36-7 (9000-series) and four ex-Western Pacific GP40's (900-series) assigned to the MP by Union Pacific. All three models wore UP colors with "MISSOURI PACIFIC" in MoPac's Little Rock style lettering on the sides of the long hood.

With a quick touch-up at the paint shops with the word "UNION" over the lettering, by the mid 1990's the MoPac name drifted into oblivion.

      the SD45 - MoPac... Yet Still Union Pacific

The SD45s were in service for a short 13 months, and many would ultimately fail while in hump service in the yards of Little Rock and Fort Worth. In fact, UP #6 below caught fire shortly after the photo was taken, and the unit was taken out of service immediately, never to run again. (J. Glenewinkel)

These units never wore the 'Missouri Pacific' lettering and usually are not included in official MoPac power rosters. We've included them here as an interesting footnote to Missouri Pacific's final days.

UP SD45 #4, U30C #2950, and SD45 #41 - are begin a deadline of retired units in Fort Worth, Texas in 1985. The ownership of UP #4 was transferred over to the Missouri Pacific, while the #41 was still owned by Union Pacific. All three units including the U30C were used in hump service in Fort Worth in 1984 and a portion of 1985. - Jay Glenewinkel Photo


UP 6 - In late 1983, and 1984, several Union Pacific SD45s were taken out of storage in Yuma, Arizona, reconditioned and placed in service on MoPac rails to help relieve the Missouri Pacific of their power shortage. These SD45s include 1, 6, 8, 9, 11, 17, 20, 21, 23, 31, 36, 41, 45, and 47. - Jay Glenewinkel Photo

UP 32 - Ownership of at least 6 of these SD45s was transfered over to the Missouri Pacific on March 13, 1986. These SD45s include 4, 6, 17, 32, 41 and 48. - Jay Glenewinkel Photo

UP 41 - MoPac SD45s numbers UP6, UP32, UP41, UP48 (they never wore the MoPac name as the ex-Western Pacific GP40s did) are pictured here at Centennial Yard in Fort Worth, Texas in 1984. - Jay Glenewinkel Photo

UP 48 - Jay Glenewinkel Photo

The UP SD45's were used in general service, although not normally on priority freights. Several of them were used in Illinois for a time in coal service. They had their ups and downs, mostly the latter as they were less than stellar performers. Being in storage for an extended period can take its toll on units as the contacts tend to rust and fuel in the tanks develops an algae that clogs filters and fuel systems.

There were tried unsuccessfully in hump service at several locations including North Little Rock and Centennial Yard in Fort Worth. They tended to "soup up", that is pool lube oil at low engine speeds and during periods of extended idling, and then blew oil out all over the place when revved up. This can be common on Roots Blower engines that sit and idle for extended periods such as the GP38 series. It is also somewhat common for the turbocharged SD45's as well. I have seen this phenomenon with SD45's on several railroads. This is why you may see oil around the top and sides of carbodies on GP38 series units that are captive to yard and local service for extended periods and that may sit and idle for extended periods, such as over weekends.

IIRC; they were back in storage in about a year after coming to the MoPac side. (Tuch)



From Bluebirds to Canaries

MoPac's older fleet originally delivered in Jenks Blue were slowly but surely painted into the Union Pacifc scheme with "Missouri Pacific" block-style lettering. This would be the final scheme before the eradication began of the MoPac name a dozen years later.

This pair is special. These two locomotives were coupled together when I caught them having come in on a northbound like this. What do you suppose the odds are of this happening? It certainly isn't too likely to happen again, although with UP's latest renumbering scheme nowhere near complete, I suppose there is that possibility.
