Between 1854 and 1929, 250,000 orphans and abandoned children were placed on East Coast city trains and sent west to live with new families. A desperate solution to a desperate problem, some of the stories turned out well and some far from well. The remarkable stories of these riders live on through their descendants, many of whom continue to search for answers about their ancestry. Mo talks to one of these descendants and tracks down the last surviving Orphan Train rider. This episode originally aired on December 20, 2019.
