Features all real trains. First stop is the Railroad Museum at Union Illinois. We learn how a steam engine works, ride in the cab of a big diesel, and see the museum's most popular train - the gleaming Denver Zephyr glide down the tracks. Next stop - Europe - where we see sleek streamliners, electrics, trolleys and passenger stations in Spain, Portugal, Italy, and France. We visit the Harbor Belt just outside Chicago to learn how a freight train is put together. We learn about classification, signaling, and how a hump yard works.
