The Twin Star Rocket was a passenger train operated by the Chicago, Rock Island and Pacific Railroad.

Introduced on January 14, 1945, it was the only new streamlined train permitted to enter service in World War II by the U.S.

[1] The new train became the second longest north–south train itinerary under the management of a single railroad in the United States (and the longest measured by great circle distance) with its northern terminal at the Milwaukee Road’s Minneapolis depot and southern terminal 1,363 miles (2,194 km) away at Houston, Texas.

At Kansas City the southbound Twin Star Rocket added a lightweight 8-section, 5-double bedroom sleeping car for the overnight run to Houston.

The Twin Star Rocket served Saint Paul Union Depot, Albert Lea, Des Moines, Kansas City, Topeka, Wichita, El Reno, Fort Worth and Dallas en route to Houston from Minneapolis.
