1996-1997
This first group of news and changes to UP's locomotive fleet was done for publication in the Locomotive Notes II, a special news section published as part of Diesel Era magazine for two years, from Volume 7, Number 1, January/February 1996, to Volume 8, Number 6, November/December 1997.
May-June 1996 (portions used in Diesel Era, Volume 7, Number 5, September/October 1996, page 58)
July-August 1996 (portions used in Diesel Era, Volume 8, Number 1, January/February 1997, page 54)
September-October 1996 (portions used in Diesel Era, Volume 8, Number 1, January/February 1997, page 54)
November-December 1996 (used in Diesel Era, Volume 8, Number 2, March/Aril 1997, pages 59, 60)
January-February 1997 (used in Diesel Era, Volume 8, Number 3, May/June 1997, page 60)
March 1997 (used in Diesel Era, Volume 8, Number 4, July/August 1997, page 56)

(The Locomotive Notes II news section of Diesel Era was discontinued after Volume 8, Number 6, November/December 1997.)
1998-2000
This group of news and changes to UP's locomotive fleet was done for distribution via email and internet news groups; first on the original Streamliner newsgroup, then later on LocoNotes. I started the LocoNotes newsgroup in November 1998 in part as a place to share this information.
- 1998 highlights were used in the 1999 locomotive directory
- 1999 highlights were used in the 2000 locomotive directory
- 2000 highlights were published in Diesel Era, Volume 12 , Number 2, March/April 2001, page 45
For a myriad of reasons, in January 2001 I stopped keeping track of the changes to Union Pacific's current locomotive fleet, and Jim Harrawood took up the challenge with his UP Changes web page. (The status of Jim Harrawood's UtahRails.com web site is uncertain following his death in January 2006.)
A Union Pacific 2001 Locomotive Directory, covering the year 2000, was prepared, matching three previous directories in content and format, but was not published.
As of September 2005, all the known changes are again being incorporated, but I'm not doing any background research or analysis. It is a minimal effort, meant to simply keep the roster up to date.
