By 1940 they were all gone, but for a generation it was streetcars that dominated the streetscapes of both Duluth and Superior, Wis.
In a new book, author and train enthusiast Aaron Isaacs extensively details the history of the bygone trolley era. Given Duluth's geographic dimensions as a long, hilly and not very wide city, there were unique ways constructed to accommodate, including using a bridge (that no longer exists) to connect Duluth streetcars with Superior. The area was also known for building the Incline Railway, which carried passengers up the famous Duluth hillside, and the only known firefighting trolley in the US, which responded to emergencies along Park Point.
Isaacs joins The Daily Circuit to talk about his book, "Twin Ports by Trolley."
