Question: was there a railroad in the underground railroad

Answer: No, The escape network was not literally underground nor a railroad. It was figuratively ``underground'' in the sense of being an underground resistance. It was known as a ``railroad'' by way of the use of rail terminology in the code. The Underground Railroad consisted of meeting points, secret routes, transportation, and safe houses, and personal assistance provided by abolitionist sympathizers. Participants generally organized in small, independent groups; this helped to maintain secrecy because individuals knew some connecting ``stations'' along the route but knew few details of their immediate area. Escaped slaves would move north along the route from one way station to the next. ``Conductors'' on the railroad came from various backgrounds and included free-born blacks, white abolitionists, former slaves (either escaped or manumitted), and Native Americans. Church clergy and congregations often played a role, especially the Religious Society of Friends (Quakers), Congregationalists, Wesleyans, and Reformed Presbyterians, as well as certain sects of mainstream denominations such as branches of the Methodist church and American Baptists. Without the presence and support of free black residents, there would have been almost no chance for fugitive slaves to pass into freedom unmolested.
