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, a land-speed-record-setter, was scrapped. It is the only surviving locomotive of its class and was listed on the National Register of Historic Places in 1979.

The E7s-class was created by upgrading the valves in the cylinders on the E2a, E2b, and E2c-classes from slide valves to piston valves. An additional change from the E2 to the E2a,b,c and subsequent E7s class included the use of a Belpaire firebox instead a "radial stay" firebox.
The original 7002 was an E2-class locomotive built in 1902 by the Pennsylvania Railroad's Altoona Works in Altoona, Pennsylvania. On June 11, 1905, the Pennsylvania Railroad inaugurated its new 18-hour train service from New York City to Chicago, the Pennsylvania Special—forerunner to the famed Broadway Limited. 7002 was coupled to the train as the replacement locomotive in Crestline, Ohio. Delays east of Mansfield caused it to depart Crestline 25 minutes late.[2] 7002 set an unofficial land speed record of 127.1 miles per hour (204.5 km/h) near Elida and arrived on time in Fort Wayne, Indiana.[a] It was scrapped in 1935.
8063 was an E2a-class also built in 1902 by the Altoona Works. It was upgraded to the E7s-class in 1916. 8063 was renumbered, altered to resemble 7002 and placed on exhibit as the "world's fastest steam engine" at the 1939 New York World's Fair and the Chicago Railroad Fair in 1948–49.[3] 7002 was transferred to the Railroad Museum of Pennsylvania from the Pennsylvania Railroad's historical collection in Northumberland, Pennsylvania in December 1979 by the Pennsylvania's successor Penn Central.[4] 7002 was listed on the National Register of Historic Places on December 17, 1979. In the 1980s, 7002 was leased to and operated by the Strasburg Rail Road, often double-heading with PRR 1223. Both 1223 and 7002 were removed from service when the Strasburg Rail Road acquired an ultrasonic testing device in December 1989 and discovered that the metal sides of the locomotives' fireboxes were too thin to allow for safe operation.[5] The locomotives were moved across the street, to the museum.
a. ^ The record was never verified and was often disputed. The New York Times believed the claims to have been exaggerated with the speed being closer to, a still respectable, 70–80 miles per hour (110–130 km/h).[6]
