Burlington still had plenty of trains operating in 1965. The only substantial difference between this timetable and the 1961 timetable shown a few days ago is to the Minneapolis-St. Louis route.
That route was served in 1961 by the Zephyr Rocket, a train that began operating in 1941 as a joint service of the Rock Island and Burlington railroads. It ran over Rock Island tracks from Minneapolis to Burlington, and Burlington track from there to St. Louis. An overnight train, it included coaches, a diner, and sleeping cars. The train still appears in the 1965 timetable, but it has lost its diner, its sleeping cars, and its name, being simply designated #15 northbound and #8 southbound. The 1961 timetable also had a coach-only train from St. Louis to Quincy that was dropped from the 1965 timetable.
