While researching the Nancy Hanks train which went from Savannah to Atlanta between 1947 and 1971, plus briefly in 1893, I discovered the Central of Georgia Railway Historical Society at www.cofga.com.
They have some great photographs on their website and in their newsletters. The photo below appeared in their Jan.-March 2021 newsletter.
This 1957 photograph of a Nancy Hanks billboard at the intersection of Abercorn Street and East 40th Street in Savannah is shared with permission from the collection of the Central of Georgia Railway Historical Society.
To read my full article on the Nancy Hanks, Airline Belle and Man O war trains go to the website of Appen Media and the Dunwoody Crier and search any of these engine names.
You can also find other local history articles by searching under Past Tense on the Appen Media website.
