Union Pacific Caboose Painting, Lettering & Numbering
Index For This Page
This page was last updated on August 19, 2011.
The following information was compiled by Dick Harley in answer to questions concerning the paint used by Union Pacific for their cabooses. This was in aid of two projects that are restoring two separate Union Pacific cabooses: UP 25510, a steel CA-8 being done in Kansas City; and UP 25722 (UP 3576), as wooden CA-1 being done in Fife, Washington.
UP C.S. 22 was Union Pacific Common Standard 22, which defined UP paints and where they were applied.
These colors were used from 1947 to the end of cabooses in the 1980s.
The year is listed after the paint manufacturer's numbers.
All of these came from UP approved vendor lists. There were more vendors for a few colors, but these were the names most recognized.
The "Pantone match" is a best guess, but is often not an exact match.
