🇺🇸 United States ·built by Altoona Works· from 1869· class of 67 American 4-4-0 locomotives
what is it?
The Pennsylvania Railroad's steam locomotive class D3 (formerly Class C, pre-1895) comprised sixty-seven 4-4-0 locomotives intended for general passenger and freight service, constructed at the railroad's own Altoona Works (now owned by Norfolk Southern) during 1869–1881. They were the third standardized class of locomotives on the railroad and the most numerous of the early standard types; they shared many parts with other standard classes. This design differed from the Class A (later D1) mainly in its smaller drivers for greater tractive effort for freight haulage.
