The Pennsylvania Railroad's no. 2512 was a single de Glehn Compound 4-4-2 "Atlantic" type locomotive that the railroad imported from France in 1904.

Background

Upon observing the success of compound locomotives designed by Alfred de Glehn in use on various French railways, the Pennsylvania believed that such a design could inspire their engineers and thus decided to purchase one of de Glehn's designs. While the engine would be grouped with the class E locomotives being of the 4-4-2 arrangement, it did not receive a formal classification, as it was a single experimental design. The engine was featured at the Louisiana Purchase Exposition in 1904, but was found to be too light for the Pennsylvania's use^[2] and saw little service beyond their shops. The engine was retired by 1912, and scrapped.^[3]
