This is the tender for a coal-burning 4-4-2 steam locomotive that was built by Altoona Works in January 1902. The engine is on display at the Railroad Museum of Pennsylvania in the town of Strasburg.

From museum signage: "Using speed as their primary marketing tool, nineteenth century railroads competed fiercely for passenger business. The New York Central Railroad was the first to break the 100 miles per hour barrier in 1893. Not long after, the Reading Company had four Atlantic-type locomotives of their own in service capable of running 100 miles per hour. The Pennsylvania Railroad's mechanical engineer Axel Vogt designed the railroad's first high-speed Atlantic, a Camelback, in 1899. Although mechanically sound, the railroad disliked the centered cab of the Camelback, and subsequent Atlantics were built to the more traditional design.

The E2 and similar E3 class Atlantics that followed quickly developed a reputation as fast, dependable runners. One E2, Number 7002, gained fame on June 12, 1905 when it reportedly set a ground speed record of 127.1 miles per hour. Running late with the Pennsylvania Special, engineer Jerry J. McCarthy was making up time west of Crestline, Ohio. Although unsubstantiated and often debated, no higher claims have ever been reported.

Many E2 and E3 Atlantics were later rebuilt and added to the E7 class, serving well into the 1920s.

The Pennsylvania Railroad would continue to use speed for its publicity long after Number 7002 made her record setting run. In 1939, seeking to once again capitalize on the event, the Pennsylvania Railroad prepared to send Number 7002 to the World's Fair in New York. Unfortunately, the famous locomotive had been unceremoniously scrapped in 1934. A similar E7 class Atlantic, Number 8063, was chosen and cosmetically altered to look closer to the original Number 7002. Renumbered, the locomotive went to New York and became part of the Pennsylvania Railroad's historic collection.
