Frank A. Weer (1932-2019) was an employee of the Reading Company and an enthusiastic photographer of all things related to railroads, specifically in Pennsylvania. Fascinated by trains from a young age, Weer spent time taking photographs of the passing rolling stock. He developed his own photographs, and over time, he established a vast collection of photographic prints of steam locomotives and other rolling stock, as well as the railroad tracks and structures with which the railroad was affiliated. The Reading Company, where Weer worked for thirteen years, was an influential railroad company that served the economic development of the Greater Philadelphia area for over 100 years. Before it became a booming passenger railroad, the Reading Company began transporting anthracite coal. The passenger "ridership" of the Reading Company reached its peak in the 1950s. The company went bankrupt in 1971, and the passenger services were taken over by the South Eastern Pennsylvania Transportation Authority by 1974. This collection documents the construction and expansion of the Reading Railroad and the company's tangible property and human resources throughout the twentieth century. The collection consists of negatives (glass plate and film), photographic prints, and color slide transparencies. The creator established a chronological order, which has been maintained. The collection is arranged into five series: Structures and objects, Passenger stations, Rolling stock, People, and Frank A. Weer's personal slides.

This collection consists of glass plate negatives and photographic copy prints which were made directly from the negatives. The images document an array of subjects, though the majority of the images are of locomotives, railroad cars, railroad stations, and other railroad infrastructure. Various landscape and cityscape photographs are also included. Where it is possible to identify the locations, the majority of images document sites in Pennsylvania, though photographs of sites in New York state and Ontario are also present.

The Northern Liberties & Penn Township Railroad Company was incorporated in Pennsylvania on April 23, 1829, to build a railroad from Front Street at the Delaware River through what was then the independent District of Northern Liberties and Penn Township (now both part of the City of Philadelphia) to connect with the state-owned Philadelphia and Columbia Railroad near Broad and Vine Streets. This volume is the basic surviving record of the company's monetary transactions during its period of construction and independent operations.
