b. January 1960 -- "NEW HOME FOR THE HYBRID: Union Pacific, a railroad known for variety in motive power, has picked up an odd one: Bamberger Railroad diesel 570, now UP 1270. Bamberger (which folded last year ) got the early road-switcher from Alco-GE in 1943. Although the few units built up to that time had been partly requisitioned for wartime use in Iran, the Utah electric rated One complete with heating boiler (and a trolley pole to throw signals ) for its troop trains. The Alco's silhouette became truly unforgettable in 1951, when upgrading at La Grange gave it an EMD hood." (Trains magazine, January 1960, page 14)

Number
Known Disposition
  UP 1204 To David J. Joseph Co. (DJPX) 1204, leased to Fort Wort & Western Railroad (FWWR) for four months during 1999, to Chaparral Steel at Petersburg, Virginia, later in 1999 as number L409-2. (information from Randy Keller via email on February 27, 2007)
  UP 1205 Sold to Mobile Locomotive Service, moved to Lake Terminal (Kobe Steel), Lorain, Ohio in November 1998 and January 1999.
  UP 1218 Sold to Mobile Locomotive Service, moved to Lake Terminal (Kobe Steel), Lorain, Ohio in November 1998 and January 1999.
  UP 1223 Sold to Mobile Locomotive Service, moved to Lake Terminal (Kobe Steel), Lorain, Ohio in November 1998 and January 1999.
  UP 1228 Sold to Mobile Locomotive Service, moved to Lake Terminal (Kobe Steel), Lorain, Ohio in November 1998 and January 1999.
  UP 1237 (2nd) Sold to Mobile Locomotive Service, moved to Lake Terminal (Kobe Steel), Lorain, Ohio in November 1998 and January 1999.
  UP 1241 (2nd) To (leased?, sold?) CF Industries, Donaldson, Louisiana, then to Clinton Terminal (CRT), Clinton, North Carolina.
  UP 1284

Lost in transit and returned to UP in December 2000 (still painted full UP yellow and gray), stored at Houston until sale by auction to Larrys Truck Electric in August 2002, moved to LTEX at MacDonald, Ohio, still there as of November 2011. (Note that this is not the SW10 that is lettered as NREX 1284, which is ex CP 1284, originally UP 1221.)

UP 1284 was shown on a list of locomotives sold to David J. Joseph Co., but research will always show that a list is simply a list.

Although UP 1284 was reported as being sold to DJJ in July 1998, a report was shared on the LocoNotes Yahoo group that UP 1284 was interchanged from CSX to UP at New Orleans on December 2, 2000, which indicates that it had been someplace other than on UP tracks between 1998 and 2000. Further research found that DJJ bought it in 1998, and moved it to an unknown location. Due to its lack of suspension and some air brake problems, its movement by interchange was limited and required special attention, and it got lost. It was photographed in Georgia in October 2000, and it showed up on UP's door step in December 2000 in New Orleans.

UP 1284 landed at UP in New Orleans in December 2000, because it was lost on CSX and clearly marked as Union Pacific. The AAR rule is that when in doubt, send it home. There was no paperwork on board the little locomotive, and UP had no paperwork in Omaha, not even anything saying that DJJ had bought it. The person usually in charge of locomotive history and sales had retired on September 1, 2000, and the position was vacant when UP 1284 was returned to UP rails. Apparently, no one else knew anything about the locomotive records, or how to access them on UP's computer system. Possession is 9/10 of the law, and it was clearly marked for UP. It was sent to Houston pending further action. It was stored pending identification of the owner, but nothing happened, so it was sold in 2002 to Larrys Truck Electric (LTEX) for a reported $4000, basically its scrap value because of the condition of its internal components. LTEX reportedly bought it as a parts source.

c. UP added side handrails for improved safety.
d.

Assigned UP 1275-1284 series in February 1985, in number sequence after UP's SW10s 1200-1274; assigned UP 1000-1014 series in May 1985, with the pending arrival of five additional units, which became UP 1010-1014.

General Notes:

a. Fueled by natural gas; assigned to switching service in Los Angeles area from September 1994 to July 1998.
b. UP 1298 was built using frame of retired Boston & Maine GP9 1729, frame number 7549-03, serial number 23227; completed in November 1993; completed unit remained at Boise for testing; unveiled in public ceremony by the newly organized MK Rail at Boise on 13 January 1994.
c. UP 1299 was built using frame of retired Seaboard GP9 2358, frame number 5024-02, serial number 10548.
d. Both units entered service at Salt Lake City, Utah, on 12 July 1994; transferred to Los Angeles on 27 July 1994; both units were out of service at Los Angeles until special fueling facilities could be completed during September 1994.
e. Lease expired, and units returned to Motive Power Industries (successor to MK Rail), 1 July 1998; stored at Boise until 2005 when they were leased to BNSF for use on Los Angeles Junction Railway, along side the two other MK1200G units leased by AT&SF (later BN, then BNSF) to LAJ; in service as BNSF 1202 and 1203 until mid May 2012, then stored pending return of all four units to MK (Wabtec).
f. Assigned UP 98 and 99 in December 1997, not renumbered prior to retirement.
g. Sean Graham-White wrote the following in an article published in 2002 in CTC Board magazine: "M-K chose a straight LNG system rather than dual-fuel because they believed the latter is harder to control. One disadvantage was that the combustion technology available when the units were built resulted in reduced engine RPM (1500 vs. normally 1800) meaning a reduction in horsepower from 2000 to 1200."
