The Pennsylvania Railroad DD1 was a class of boxcab electric locomotives built for the New York Tunnel Extension, which brought the railroad into the original Pennsylvania Station through the North River Tunnels. The railroad built 66 at its Altoona Works, with Westinghouse supplying the electrical equipment, and they entered service in 1910. They ran in semi-permanently coupled pairs, each pair being in effect two 4-4-0 locomotives back to back, on 650 volt direct current from a third rail. Each unit was rated at 1,580 horsepower, and top speed was 85 miles per hour. Most later moved to the Long Island Rail Road, and the pair numbered 3936 and 3937 is preserved.
