The Aerosport Rail is an American minimalist ultralight aircraft, designed by Harris Woods and built by Aerosport Inc. The aircraft was first flown on 14 November 1970. Included in this category due to the dual engines. The Rail is little more than a 2 by 5 inch squared aluminium tube (rail) with all-metal wings and a T-tail. The pilot sits on the tube, just ahead of and above the wings. Two small two-cycle engines derated to 25 hp (19 kW) are mounted on struts behind the seat on either side of centerline, driving pusher propellers. Individual 4 U.S. gallons (15 L; 3.3 imp gal) fiberglass fuel tanks are mounted in front of each engine. About 175 sets of plans were sold between 1970 and 1977. The follow-on design, the Aerosport Quail uses the Rail's wing design for an enclosed tractor configuration homebuilt aircraft.
