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.

Highlights of 1998 -- 1998 highlights were used in the 1999 locomotive directory

Highlights of 1999 -- 1999 highlights were used in the 2000 locomotive directory

UP Diesel Roster Updates

1998, 1999, 2000 -- Three Union Pacific Locomotive Directories were published. A fourth issue for 2001 was prepared, but was not published.

2001-2005 -- From 2001 through late 2005, Jim Harrawood posted the changes to his web site, which was discontinued after his death in January 2006.

September 2005 through June 2009 -- All the known changes from 2001 forward were incorporated in the online Union Pacific diesel roster, as a minimal effort meant to simply keep the roster up to date, without any background research or analysis.

After the updates for June 2009 were incorporated, the effort came to an end.

Maintaining a "current" UP diesel roster first started in 1988 and became a real challenge to keep up-to-date. It was a good run, but the time had come for it to stop. Time and effort would be focused on documenting all of Union Pacific's history, including steam locomotives back to 1864.
