A hand-drawn map of the electric railway trackage from Kennebunk Village to Cape Porpoise and from Kennebunkport to Biddeford. The line from Sanford through Kennebunk Village to Cape Porpoise was built by the Sanford & Cape Porpoise Railway in 1899, primarily to handle coal in carload lots from the wharf at Cape Porpoise to the mills in Sanford. This line also provided transportation to Sanford and Kennebunk residents to the Cape Porpoise Casino.

The line to Biddeford was opened in 1904 by the Altantic Shore Line Railway. This company was later taken over by the York Utilities Company. Service was abandoned to Cape Porpoise in 1925 and to Biddeford in 1927.
