Lucy is taking a picture of her friends in the Transportation Hall at the Smithsonian Intuition. Suddenly she is transported in time back to the day when the two companies working on the transcontinental railroad meet up at Promontory Summit, Utah. She is there to take an official photograph. Building the railroad was not easy and it required a lot of workers who faced some very difficult obstacles. The text mentions the Chinese laborers who took three years to lay 100 miles of track through the Sierra Mountains; other crews faced angry Native Americans who were very unhappy with the railroad crossing their homeland. Lucy does capture the big moment. She sees the golden spike driven and removed, the two train engines touch and a telegram is sent announcing the great accomplishment. It took six and a half years to build the railroad, which enabled people to cross the country in two weeks. There is a glossary that defines the bolded words found in the text and factual information about the man who dreamed of connecting the coasts and the impact that the railroad had on the growth of the country. 2003, Soundprints/Smithsonian, Ages 7 to 9.
