The Pennsylvania Railroad (PRR) A3 was a class of 0-4-0 steam locomotives built at Altoona Works between 1895 until 1905. The A3s were used as switchers for railroad cars at various PRR yards. Later, some A3s were converted to A3a, which had saddle tanks instead of tenders. The A3s were retired by 1920s, when the railroad introduced the much stronger class A5s. All members of the A3 class were scrapped.
