This timetable shows minor tinkering with schedules since yesterday’s 1954 edition. The eastbound California Zephyr left Oakland 3 minutes earlier but arrived in Salt Lake City 20 minutes later. Westbound, the train left Salt Lake 20 minutes earlier and arrived in Oakland 25 minutes earlier.

The eastbound Zephyrette schedule is advanced exactly one-half hour. Westbound, its departure from Salt Lake is unchanged but it managed to arrive in Oakland 1-3/4 hours sooner.

Other than this, the biggest change since 1954 is that Western Pacific decided to devote half of the timetable’s front cover to an advertisement for the Rail Travel Card — a credit card accepted by 57 railroads — and U-Drive-It rental cars. I can’t find any history of a company named U-Drive-It so I presume this was a generic name for rental car services.

A 1955 timetable doesn’t have an ad on half the cover, so this ad was probably added in 1956 or 1957. Pictured above is the non-advertising half of the cover, which (unlike the earlier editions we’ve seen) includes the effective date of the timetable.
