Doubleheaded GG-1s stop traffic in Aberdeen, as they head north at 80 mph with a Florida train. (Paused at the crossing are an old Checker cab, a Ford, and a Chevy Corvette, if I'm not mistaken...) This 4-lane grade crossing was always busy, with constant traffic to and from Aberdeen Proving Ground. Everything has changed here, with a pedestrian overpass now dominating the scene. Bel Air Avenue has been cut, and a new APG Road overpass carries vehicular traffic across the NEC. Lead locomotive 917 still survives, amazingly; it was built by Altoona/Westinghouse in July 1942 as the PRR 4919, retired by Amtrak after 5.5 million miles, and is today preserved at the Virginia Museum of Transportation in Roanoke.
