Here’s the 1958 edition of a brochure we previously saw in its 1953 incarnation. The main difference is that all of the photos of trains have been updated to show Union Pacific dome cars.
The Willmarth-style map that fills one side of the brochure hasn’t changed, but an inset into the map has. The 1953 edition had a United States map that outlined Union Pacific routes. The 1958 edition replaced this with a photo of one of Union Pacific’s veranda-style gas-turbine locomotives pulling a freight train along the Weber River near Peterson, Utah. This photo was also used on Union Pacific’s 1957 calendar.
