Union Pacific Railroad

General Notes:

1. Original total of 34 SP/SSW units, numbered in two groups; SP 7240-7247 and SSW 7248-7273; 32 units went to UP at merger; SP retired two units (SSW 7258 and 7267) prior to the merger.
2. Due to production schedule difficulties and delayed financial arrangements, these two groups of former SP and SSW units suffered a mix up of frames while being built. The builder's serial numbers on the builder's plates do not match the units' frame numbers, as shown in the column above. (See LN II, 179-1)
3. Assigned UP 5210-5241 in September 1997, two units (UP 5217 and 5236) renumbered; assigned UP 1310-1341 in December 1999; none renumbered prior to lease expiration and return to owner.

Notes:

2. UP 5217 (ex SP 7247, assigned UP 1317) was the first unit in this group to be repainted to Union Pacific, completed on 21 June 1997.
3. SSW 7249 (assigned UP 1319) was wrecked in a grade crossing accident on 12 November 1999 while in local service on train LOH43-11, operating out of Kaiser, California. Following the wreck, SSW 7249 was moved first to Taylor Yard in Los Angeles, then to North Little Rock, Arkansas, in April 2000 for repair. The unit had a bowed frame, side sill damage, a shifted prime mover, and damaged end sills and end sheets, along with a damaged draft gear pocket. There was some delay before repairs could be completed due to the insurance settlement from the wreck. A settlement was reached and the unit was repaired at North Little Rock and returned to the owner, with the above 7 June 2000 retirement date. It was moved to VMV Enterprises at Paducah, Kentucky, on 2 June 2000.
