How many stations were there along the underground railroad?

The Underground Railroad was not a formalized system with fixed stations; rather, it consisted of a network of secret routes and safe houses used by enslaved people escaping to freedom. Estimates suggest there were thousands of "stations" or safe havens, often run by abolitionists, free Black individuals, and sympathetic allies, spread across various states, particularly in the Northern United States and Canada. The exact number is difficult to determine due to the clandestine nature of the operation.
