The old train station was built in the late 1800s for the Central Railroad of New Jersey. Today, it serves as a hub for the Califon Historical Society and access point for the Columbia Rail Trail. Supposedly, the name Califon comes from a shortening of "California", since the painter creating the station map didn't leave enough room for the original title.
