This colourful publication represents a worthy effort by the Missouri Pacific Lines (popularly known as Mo-Pac) to inject some excitement into marketing its services. Styled as the Route of the Eagles it operated a network of passenger and freight trains based in the Midwest city of St. Louis. It was the era of diesel powered streamliners and MPL offered five named trains under their Eagle branding to a choice of destinations, from Omaha in the northwest and the Gulf of Mexico to the south. The aquiline association was chosen from employee suggestions in 1940. The attractions of Pullman roomettes and observation cars were described in detail to tempt passengers on to the trains. Freight handling services featured prominently, including a helpful timetable confirming that a consignment departing Baton Rouge at one minute after midnight on a Monday would reach St. Louis at 3am on Wednesday.
