In the mid 19th century, thousands of children roamed the streets of New York in search of money, food and shelter. In an ambitious and controversial effort to rescue them, between 1854 and 1929 more than 100,000 of these so-called "street Arabs" were sent by train to the Midwest to begin new lives in foster families. Poignant and powerful are the memories of living "Orphan Train" riders who vividly recount their experiences.
