PRR 7002
}} PRR 7002 is a Pennsylvania Railroad E7s steam locomotive located in the Railroad Museum of Pennsylvania, outside of Strasburg, Pennsylvania in the United States. Originally 8063, it was renumbered 7002 after the original, claimed to be a land-speed-record-setter, was scrapped. It is the only survivor of its class and was listed on the National Register of Historic Places in 1979. == Background == The E7s-class was created by replacing the slide valves above the cylinders on the E2a, E2b, and E2c-classes with piston valves. Unlike the E2, the E2a,b,c and subsequent E7s class used Belpaire firebox instead a "radial stay" firebox.
