By late 1954, Union Pacific was unhappy with how long-time partner Chicago & North Western handled UP passenger trains between Omaha and Chicago. Work to find a new route began, and on September 20, 1955, Milwaukee Road president John P. Kiley announced that they would handle UP's trains, including the flagship City of Los Angeles, starting October 30.

UP required cars in the Cities pool wear Armour Yellow and Harbor Mist Gray. Milwaukee planned to paint nearly 40 cars for the five trains, but quickly found the UP scheme less expensive to apply and more durable than its own. Starting in 1956, all non-commuter passenger cars and locos began receiving the new colors, which would remain the standard until Amtrak took over in 1971.

Modeling this exciting era is a snap with Walthers latest HO releases, featuring 13 different cars factory-finished in yellow and gray, with later styles of side sills, ends, diaphragms, trucks and other details.

Later style details featured on this car include:
- Build with Folded (pre-1963) or Fixed (post-1963) Car Steps - Both Styles Included.
- Notched Side Sills, 8' Nystrom Trucks w/Clasp Brakes
