Open-platform steel coach No. 581 was built in 1914 by the Pullman Company. The car was built in Lot 4298 according to Plan 2848, and was part of an order of 77 cars built for the Delaware, Lackawanna & Western Railroad (DL&W). All of the cars featured unique I-beam platform roof supports at each end, which earned them the nickname “Boontons,” as they were a familiar site along the DL&W’s Boonton Branch through Boonton, NJ. Hundreds of thousands of commuters rode these cars to and from their places of employment for over four decades. But by the early 1960s, many of the cars were considered surplus, and the Erie Lackawanna, the successor to the DL&W, began selling them to tourist railroads and museums. Coach 581 was purchased by Historic Red Clay Valley Inc., and was moved to the former Jackson & Sharp Company shop buildings at East 7th Street in Wilmington for restoration. The car returned to Wilmington & Western rails and entered tourist service in May 1966. Coach 581 weighs 108,000 lbs., has a seating capacity of 72, and retains its original Hale & Kilburn walkover seats.
Many Lackawanna Boonton coaches survive in tourist service, mostly in the eastern United States. Several Boontons are in operation at Steamtown National Historic Site in Scranton, PA, and have been restored to their original colors of Pullman Green with gold lettering.
