Beautiful watercolor illustrations combine with informative text to tell the story of train travel across The United States.  Starting with the fluster of activity on the platforms of an eastern urban train station as a commuter train gets ready to pull out, the story describes the actions of conductors and passengers and the passing views until it reaches another station where we see a passenger train just pulling out to cross the country-side.  Again we get a full description of events and sounds and sights until it pulls into a midwestern city, where we meet a freight train.  And so it goes until the overnight train crosses the Rocky Mountains and encounters a high-speed train heading into a new urban station on the west coast.  Besides being informative about all different kinds of trains, it’s a lovely example of descriptive detail.  Like a virtual cross-country field trip.
