The Burlington Route (Chicago, Burlington & Quincy) featured its famous Zephyrs on this card celebrating the railroad's centennial. Caption on back of card: "The Burlington Lines of today had its inception in the tiny 12-mile Aurora Branch, chartered on February 12, 1849. From this modest beginning has emerged an 11,000 mile network of rails reaching into 14 Midwestern states. Burlington was first to operate a railway postoffice car; first to inaugurate a Diesel streamlined train; and first to introduce a Vista-Dome car."
