PRRD7

PRR D7a #953 in its builders' portrait.

The Pennsylvania Railroad Class D7 (formerly Class A (anthracite), pre-1895) was a class of 4-4-0 steam locomotive that were used on the Pennsylvania Railroad.

A total of Fifty-eight of these engines were built by the PRR's Altoona Works (now owned by Norfolk Southern) between 1882–1891 with 68 in (1.73 m) drivers, while sixty-one of class D7a were constructed with 62 in (1.57 m) drivers.

The D7 was fundamentally an anthracite-burning version of the PRR D6, with a larger fire-grate in order to burn the slower-burning, harder coal.

None of these engines survived from the scrapper's torch so today there are no existing D7s.

Trivia[]

  • These engines have the same style of the bell, and whistle placed on the boiler as the D6.
