Leap frog railway, coney island (1905)

The film shows an unusual type of railroad car designed to go over or under an oncoming car instead of around it, as conventional railroad cars must do. Each car not only runs on tracks but also has a set of tracks over its top, permitting an oncoming car to go over it. The camera was placed close to a platform on which the passenger-laden train ran, and the over-and-under vehicle demonstrated its unusual capabilities several times.
