Notes:

1. UP 4794 (ex SP 6854) was the first (and only) unit in this group to be repainted direct to UP as an SD45T-2, completed on 24 March 1998; all others were rebuilt to SD40-2Ts prior to being repainted; UP 4794 was completed as an SD40-2T on 23 April 1999.
2. UP 4801 (ex SP 6865) and 4808 (ex SP 6830) were the first two units in this group to be completed as SD40-2Ts, completed on 10 November 1998.
3. UP 4804, as SP 6848, was first retired on 17 July 1997; reinstated for rebuilding to SD40-2T.
4. UP 4814, as SP 6835, was first retired on 20 May 1997; reinstated on 11 September 1997 due to motive power shortage.
5. SP 6855 was part of the original SP 6829-6868 group to come to UP by merger in 1996; although retired by UP on 31 December 1997 and sold to LLPX and moved by LLPX to VMV Enterprises in Paducah, Ky., like the others, SP 6855 was not rebuilt from 20-cylinder to 16-cylinder and leased back to UP, as were the other units in this UP 4794-4831 group; SP 6855 was originally assigned to UP 4819, but was found to be unusable in the rebuild program, and the UP 4819 number was used on SP 6824 after that unit was retired by UP on 29 January 1999 and sold to LLPX to replace SP 6855 in the rebuild program; after being retired by UP and sold to LLPX, SP 6855 was moved by LLPX to VMV Enterprises in Paducah, Ky., where it was scrapped.
