Delmar, known for its railroading history, is home to a unique highball signal listed on the National Register of Historic Places. Nearby, a 1929 caboose serves as museum for railroad artifacts. The highball signal and caboose are located in a small park on Route 54 at the railroad tracks. The caboose has no regular hours, so call ahead. A railroad history display is also available at the Delmar Public Library, 101 N. Bi.State Blvd. and the Delmarva Model Railroad Club posts holiday open house events for model train enthusiasts.
