The Pennsylvania Railroad (PRR) was chartered in 1846 to complete an all-railroad network across the state. Between 1855 and 1874, the PRR underwent rapid expansion and emerged as one of the two largest railroad systems in the region east of the Mississippi and north of the Ohio. In 1910, the PRR entered Manhattan through tunnels under the Hudson and East Rivers. This collection consists of flyers and a brochure for Pennsylvania Railroad special fares or trains.

The Pennsylvania Railroad Company was the largest railroad in the United States in terms of corporate assets and traffic from the last quarter of the nineteenth century until the decline of the northeast's and midwest's dominance of manufacturing. This is a collection of thirty-six blank, preprinted forms dating between 1960 and 1967, mostly related to the inspection and movement of freight cars.
