MP U30C 2989 - was built in June 1976 as MP 984. It was renumbered to MP 25, then to MP 3324 and then to MP 2989. It is seen here in a deadline of 11 U30cs at Centennial Yard in Fort Worth, TX in 1987. The unit was officially retired in 1989 by UP. - Steve Rude Photo/Jay Glenewinkel Collection.

MP U30C 2996 - was built as T&P 3331 in January 1974. It was renumbered to MP 3331, and then MP 2996. It is seen here as the last of eight units pulling a San Antonio Coal train out of the CPS plant in San Antonio in 1986. The unit failed while in service on this train. This was the final run for the 2996. - Steve Rude photo/Jay Glenewinkel Collection

MP U30C 2992 - was built in 1973 as MP 987. It was renumbered to MP 28, then to 3327, and its final number 2992. It is pictured at the service tracks at Sosan Yard in San Antonio, Texas in 1987. It was retired in April 1989. - Steve Rude Photo/Jay Glenewinkel Collection

MP 3319 - looking a curious site after losing it's cab in an accident. The power hungry MoPac ran the unfortunate U30C as a cabless "B" unit until it could be fully repaired at the shops. E. St. Louis, MO, 10/3/76 - Rider photo/Brian Paul Ehni collection

MoPac recycled all its U30C's back through GE for modifications to improve fuel mileage during the late 70's or early 80's. 

The U30C's that went back to GE were not actually rebuilt, but received electrical upgrades. They received only the electrical work. Not even any fresh new paint. These units were essentially the bastard red headed step children of the fleet. It seemed they were not particularly well maintained. The mechanical forces hated them. I can recall hearing many an Electrician and Machinist complain about them when I was hostling at Yard Center in 79 and 80.

These units were also some of the first put into storage during the economic downturn of the early 80's along with the GP35's. The U30C's also were the ones likely to fail in your consist. If you got alarm bells, it was likely a U30C that had overheated, had hot diodes or hit excitation limit. These units were generally being kept off the hot shot trains out of Chicago, CFZ, CHZ, CDZ, TAZ (later called AI) and CKZ.

The first group of these units delivered had 16 position throttles on the control stands. The oldest units were also the ones that had gong bells (like CNW units) mounted just below the window on the Engineer's side.

However, they were unlike their UP cousins. UP's U30C's were in much better shape mechanically and had dynamic brakes. (Tuch)

1/72 - MoPac's first EMD GP38-2. It would continue buying until it amassed a total of 326 units (all-time most popular model on MP).

12/72 - EMD SW1500 comes to the system.

   
MP 668 - a U23 B with MP 669. The units are in fresh Jenks Blue paint and probably getting thier first dusting of road grime on a run through Hoisington, Kansas; February 1973 - Lee Berglund photo/T. Greuter collection. ·

MP 2251 - Beautiful shot of a B-boat followed by a 40-2 with TOFC train. The GE-built U23B (built 1/71 at 2,250 hp) , along with the U30 C's were the first units for MoPac to order from a manufacturer other than the largely favored EMD. Texarkana, TX, 6/76 - © Brian Paul Ehni photo

MP U23B 2263 - was built in 1974 by General Electric. It was later renumbered to MP 4513, and then into the UP number series as UP 547. It was retired in January 1991. - Robert Pollaed Photo/Jay Glenewinkel Collection

MP U23B #4525 - was built as MP 2276 in June 1976. It was later renumbered to MP 4525, and then to Union Pacific #559. It was retired in May of 1990, and was scrapped in October 1991. The 4525 is pictured in San Antonio in 1986. - Jay Glenewinkel Photo

MP 4528 - seen once again. The MoPac's U23B's had the bad luck of a high percentage involved in wrecks for the number of locos on the system. A number of these units in turn needed cab replacment, and since MoPac had EMD parts readily on hand, the GE units were fitted with the boxier EMD-style crew cabs. Hybrid units, like #4528(now in it's third numbering), would have a look distinct to the MoPac. Chicago, Ill, 11/4/89 - © Brian Paul Ehni photo

The Last Days of the Covered Wagons

As passenger service disappeared across the nation to be taken-over by Amtrak in the early '70's, MoPac's steamlined but aging F7's, F8's and their B-units found a new if less glamorous life as they began filling-out freight-hauling rosters.
